I'm new to this forum. Im very worried about my baby. She's 5 weeks old and 7 lbs and 4 oz (born 6 lbs and got down to 5 lb 4 oz). She spits up almost every time I burp her after she eats. About 2 weeks ago my doctor told me to start giving her 2 oz top off-s of formula 3 times a day in addition to breastfeeding her. She spits up breast milk a LITTLE bit more than formula but she really spits up both of them. When she spits up, it often comes out of her nose and she chokes on it and has labored breathing while this is happening and for a minute or 2 afterwards. We have tried EVERYTHING from shorter, more frequent feedings, burping often, to keeping her upright. I got her an incline sleeper which she sleeps in so she is never in a flat position.. i just dont know what to do at this point. My pediatrician keeps telling me its normal for a newborn but how is she ever going to gain weight if she spits up everything she eats? Its also very scary when the spit up comes out of her nose and she chokes. We ended up taking her to the ER last time it happened and the resident there gave me Zantac to give her. I don't want to give it to her. Tried it once and it was HORRIBLE. Does it sound like she actually has reflux? does anyone have experience with this?
