D.L.
My daughter did not vomit when she cut her first teeth. She's 9 1/2 months now and still cutting teeth. I know a tooth is about to pop through because 1-3 weeks prior she is very irritable, her nose is constantly running and she gnaws on ANYTHING & EVERYTHING and drools like a MANIAC!!!!! Her sleep pattern alters sometimes too, but I think that's because she wakes up in pain. I use motrin or infant tylenol and orajel swabs which helps her mood a great deal :) I also let her chew on freeze pops (still in the package of course). The cold gives her a lot of relief.
BUT...of course as "they" always say, if you have any questions or concerns, it's best to call your PED. I'd be concerned about the vomitting too. My daughter had reflux since 2 weeks old and I was back & forth to the Dr at least once a week for a month & a half! What a nightmare!
Good luck!!!
