zaks two bottom teeth have just broke thru the gums and he has been in obvious pain with them. will this put him off his feeds ? instead of his usual four 7-8oz bottles a day, he is now having 5-6oz four times, maybe 5 times. so he is having around about the same a day, if not a little less. is this just cos of his teeth? or is it a sign of something else ? anyone else experienced this ?
