My 5 month old daughter was sick yesterday afternoon (3 yo daughter has been sick since Sunday and I have stomach ache/was sick last night). She then proceeded to be sick every hour or so, all through the night as well. She had a bottle of milk this morning, which stayed down for several hours, but subsequent bottles have come straight back up. LAst night she was extremely lathargic. Usually she wiggles her arms or legs constantly and gurgles & goos, but she just laid there with her eyes half shut. This morning she was a bit more back to normal but now if very quite/still again.
How long before we take her to the doctors/hospital??
