M.A.
he should be ok, but call the doc just in case. Hopefully it will never happen again but if it does here are some tips. while you and him are up playing like that, check his eyes and make sure they are not dilated. (they might be a little, but should return to normal if not call a doctor) Also check his eye flow with you finger or toy he likes, left right, then up down. he may not follow the whole thing cause he's young but most of it. and if you feel the need to stay up and keep watch over night just tickle his feet for a reponse. if you don't get a movement, then there is a problem. Since you feed him and he didn't throw up thats a good sign too. Good luck and get some rest!
