Concerned First-Time Mom: My 16-Day-Old Baby is Lethargic and Not Feeding Well

2/8/2026, 7:40:28 PMMale25-34

Hello, everyone. I’m reaching out as a new mother who's going through a challenging situation. My journey through pregnancy was difficult, marked by severe morning sickness, sciatica, and fewer fetal movements, but luckily, all the ultrasounds yielded positive results. I gave birth at 39 weeks and 4 days through induction and had a vaginal delivery. Our daughter arrived healthy, weighing 3.3 kg (7 lb 4 oz), although I faced complications during childbirth, including issues with the placenta and considerable blood loss, which made it quite traumatic for me. For the initial two weeks, my baby thrived. She showed a strong appetite, and we practiced combination feeding since my milk supply is limited, relying mostly on bottles. She was feeding appropriately, and we noticed a good number of wet and soiled diapers, plus she was usually alert when awake and maintained normal sleep patterns. However, yesterday when she was 15 days old, I noticed a significant change. After waking up at 6 AM, she slept for an extended period of five hours, contrary to her typical two-hour naps. Upon my attempts to wake her for a feeding, she struggled to stay awake. Whenever I tried to feed her, she promptly dozed off, was unresponsive, and had difficulty drinking. We ended up taking her to the hospital where the medical team suspected an infection. They performed blood tests, urine analysis, and even a lumbar puncture. So far, there hasn’t been any fever or clear indication of infection, though we're still waiting on the results of some cultures. She remains excessively sleepy and continues to fall asleep while feeding, which has led to reduced intake. In the past 18 hours, she's only had around six wet or dirty diapers, which is on the low side, especially compared to her previous outputs. A particularly distressing incident occurred in the emergency department when I noticed her hands and feet tremble; it was alarming since she’s never experienced that before. I’m feeling scared and anxious without concrete answers from the doctors. If we continue to receive negative test results, I worry that we may be discharged with a lethargic baby who is struggling to feed and exhibiting unexplained shaking. I’m unsure how to keep her awake long enough for her to eat adequately, and I’m deeply concerned about potential weight loss. Emotionally, I’m overwhelmed. The experience of nearly losing my life during childbirth weighs heavily on me, fueling my anxiety. I would appreciate it if you could approach my situation with kindness; I am not seeking judgment. If anyone has gone through something similar or has any insights, it would mean a lot to hear from you.

I'm truly sorry to hear about the challenges you're facing as a new mom. It’s completely understandable to feel overwhelmed and anxious, especially after such a difficult pregnancy and delivery. Your concerns for your baby's well-being are very valid, and I want to provide you with some support and practical steps that may help.

Main Points

Your 16-day-old baby’s lethargy and difficulty feeding can be concerning, especially given her history and your recent experiences. While the hospital is running tests to rule out infections, it’s crucial to keep an eye on her feeding and hydration status.

Explanation

Lethargy in newborns can have various causes, including infections, metabolic issues, or even dehydration. The trembling you observed can sometimes indicate a low blood sugar level, especially if she’s not feeding well. It's good that you sought medical attention, as they are best suited to identify any underlying issues.

Prioritized Next Steps

  1. Continue Monitoring: Keep closely observing her feeding patterns. If she continues to struggle to stay awake during feedings, it may be helpful to try feeding her in different positions or gently stimulating her (such as through light rubbing on her back or feet) to help keep her awake.

  2. Feed Smaller but More Frequent: If possible, offer small amounts of formula or breastmilk every 1-2 hours instead of waiting for her to show hunger cues, as she may need gentle encouragement to take in enough volume.

  3. Stay Hydrated: Ensure she’s receiving adequate fluids. Even if you’re worried about her not feeding sufficiently, any milk or formula is better than none. If she does not seem to be able to take anything, maintain contact with the healthcare team.

  4. Document Symptoms: Keep a diary of her feeding amounts, number of wet/dirty diapers, and any other symptoms. This information can be valuable to the medical team, especially if her condition doesn’t improve.

  5. Reassess Immediately if Symptoms Change: If you observe any severe changes in her condition, such as significant tremors, unresponsiveness, or if she appears very dehydrated (dry mouth, few wet diapers), seek immediate medical help.

  6. Emotional Support: Given the emotional toll you’ve experienced, consider seeking support for yourself as well. Whether it’s speaking with a counselor or joining a support group for new mothers, it can be comforting to share your experiences with others who understand.

It’s great that you sought help quickly, and I hope you receive clearer answers soon. Remember that you’re not alone in this, and it’s okay to ask for assistance when you need it. Take care of yourself, and I’m here if you need further support or information.

Unusual Back Pain Leading to Abdominal Discomfort and Sleep Disruption

At 45 years old, standing 175cm tall and weighing 93kg, I have been grappling with an unsettling pain that begins in my right shoulder area and extends down toward my lower back. Over time, this discomfort intensifies, and after several hours, I am often hit with a stomach ache that has a cramping nature. This series of symptoms correlates distinctly with nighttime hours, as the pain in my shoulder typically emerges in the late afternoon. On particularly severe nights, I find it nearly impossible to fall asleep before 3 or 4 am, by which point the pain has faded. I typically manage to alleviate the discomfort with a dose of drotaverine, but the resolution of the entire episode can be quite prolonged. When the stomach pain arises, I feel an urgent need to use the restroom almost every half hour, with my stools consistently being soft and sometimes floating. I have undergone an endoscopy, which yielded negative results apart from confirming the presence of GERD. Additionally, I have completed hydrogen breath tests for both fructose and lactulose, yielding negative outcomes. Most recently, I had a Nardi test that also returned negative results. The recommendation has been to proceed with a colonoscopy next. However, I have read about the limited sensitivity of the Nardi test and its capability of yielding false negatives. Given that my symptoms mirror those typically associated with bile-related issues, I am considering whether exploring possible biliary duct dysfunction might still be a valid avenue, rather than disregarding it outright. Moreover, I have gluten intolerance and developed a negative reaction to dairy a couple of years ago, alongside experiencing worsening psoriasis in relation to these foods. It’s important to note that I do not have lactose intolerance. In terms of medications, I regularly take pantoprazole each morning and famotidine at night. I also use Vitamin D and magnesium supplements, although I don’t take magnesium consistently. In October, I began using minor amounts of creatine for my workouts, but I’ve established that these symptoms began about a year and a half ago, so I doubt any correlation. I am seeking guidance on whether pursuing further evaluations concerning the biliary duct is advisable, or if I should simply follow my doctor's recommendation for a colonoscopy. Thank you for your insights, and I would appreciate hearing from anyone who has experienced comparable symptoms to shed light on their diagnosis process.

Unexplained Dark Marks on My Foot

Greetings! I’m a 34-year-old female residing in Europe. This evening, I noticed that the sole of my foot felt quite rough and upon inspection, I discovered some unusual dark purple marks beneath the skin. Interestingly, only one foot has these discolorations. I’ll share a photo in the comments for reference. I suspect that my habit of resting hot water bottles under my feet throughout the day might be the cause. I find the warmth comforting, but I wonder if it could have caused some form of skin damage. I’m unsure if this could have potentially inflicted such harm, and if so, what steps I need to take next. Will this clear up on its own or is medical attention advisable? I weigh 43 kg and stand at 154 cm. Just to give you some context, my weight in December 2024 was 62 kg, indicating a significant and unintended weight loss. For background, I’ve been diagnosed with AuDHD recently, along with CPTSD, GAD, and depression. Currently, my medication includes: - 600 mg of Pregabalin - 50 mg of Agomelatine - 4 mg of Intuniv - Up to 0.75 mg of Xanax Any insights or recommendations on how to address this issue would be immensely appreciated. Wishing you all a pleasant night and thank you for your time! :)

Understanding the Risks of Potential C. Difficile Recurrence

A 32-year-old male, measuring 180 cm and weighing 65 kg, has faced a serious bout with C. difficile, necessitating hospitalization and treatment with vancomycin five weeks ago (PCR positive, toxin negative). Recent tests revealed that his calprotectin levels significantly decreased from 1800 to 25 last week. Today, he is starting to experience symptoms reminiscent of his previous episode, including elevated heart rate (over 110 bpm), feelings of dizziness, a fever of 38.5°C, reduced appetite, and audible bowel sounds. However, he has not yet experienced loose stools or green vomit as he did during the earlier illness, with those symptoms emerging just a day after the onset. The doctor could only accommodate him for a consultation a month later. He is wondering if it would be wise to seek urgent care if his symptoms do not worsen or if it is still crucial to consult a physician despite the current mildness of his symptoms. Fortunately, he is managing to keep fluids down and has been able to consume small portions of food, which raises hopes that he may not be facing another infection of C. difficile. Additional context from the past year includes abdominal pain appearing two hours post-meal, a 10 kg weight loss, and challenges with swallowing pills and food, for which he is awaiting an ENT appointment. An X-ray indicated that food was becoming lodged in the pyriform sinus, and he has been experiencing nighttime balance issues. Treatments with PPIs and famotidine have not yielded improvement, and a colonoscopy performed two weeks ago showed no abnormalities. Furthermore, he had his gallbladder removed nine years ago, and his bilirubin levels have consistently been above 40 µmol/L. Thank you for taking the time to read this.
