I have a bottle baby who is 5 weeks old. She is down to 2-3 bottles a day and live in the house. For now. It’s been cold. She isn’t interested in hay or grain. Anyways, she started with runny poo about 2 weeks ago. She was fine prior. The vet did a culture and everything looks good. Recommended pepto and a probiotic in her milk. These methods have not worked. She isn’t dehydrated but it makes for a mess and a lot of diaper clean up. She is very attached to me and it seems it is worse if she gets upset (crying/screaming for me) or at night time. I am getting her some friends to play with. I do have 2 dogs and 2 kids.
