For the past 3 nights, my one month old daughter has drank her entire bottle at 2 AM then right after, has thrown up her whole bottle. The first two nights was projectile vomit and last night was just a stream of vomit until her stomach was completely emptied. It seemed really mucusy and thick to me last night. She does not throw up during the day at all. I always keep her head above her stomach when feeding her, burp her after every ounce and keep her upright for at least 20 minutes after each feeding. She is on Gerber goodstart smooth HMO formula. I was wondering if anyone else is or has ever experienced this with there baby and what you did for it or just any advice for me to take. Thank you!
