Thank you for your reply.. Um yes she seems fine other then vomiting. Now she has runny stooles. Im not sure if this is normal.

I had a baby cousin who did the same thing...
I'm assuming you've taken your baby to the doctor?
Anyways I don't remember what kind of formula my cousin
had to be put on, but I remember it was more expensive and I think it had to be ordered through the hospital.

Thanks I have put her on neutramigin I think thats how you spell it but it seems to have worked thanks soo much

I just wanted to let you know that my cousin was about three months old when this started happening to her. She would hurdle her formula like something you'd see out of the exorcist. Then she would stop breathing. They thought she may have sids, but found out she had reflux. The flap in her esophagus wouldn't close and everytime she would eat the food would come right back up. She ended up go to riley hospital in indianapolis, in and had surgery to fix it and she had no problems after that. I don't want to scare you but make sure with your doctor it's just the formula she' s having a problem with. You never know anymore. Good luck and god bless! :d

If your baby seems well otherwise I wouldn't worry about it.I've been through this with both of mine. I've baby sat for lots of babies and this seems to be part of being a baby.The baby will outgrow this.Try to relax and baby will too.

Hello! My little nephew is also 3 months old and he spits up alot too. My sister learned that he was diagnosed with reflux. This is common for babies who were born pre-mature, or smaller than the norm. The babies grow out of the reflux once they reach 5 or 6 months old. Is it possible that your baby has refulx? Was your baby born pre-mature? If your baby does have reflux, they like to lay on your lap on their belly. It feels better for them then it does sitting up.
