My 9 wo daughter has bad gas pains that always wake her up/prevent her from napping. If I do get her to sleep, she often wakes up because she's spit up! And it takes up to an hour or more to get her to sleep, which is way too long to attempt to keep my 2.5 yo son quiet so she can fall asleep! When does it stop??
Re: When Do Babies Stop Being SO Gassy and Spitting Up All the Time?!
Most definitely could be something in your diet if you are breastfeeding. Might be time for an elimination diet to see if that helps.
FWIW, my son spit up until he was a year old. Sorry.
