On a whim yesterday, I gave Charlie Mouse 2 oz of regular chocolate milk mixed with her lactose free stuff. No problems. So today she got 2 oz of 1% mixed in for breakfast, 3 at lunch, and about 4 at supper. All with no problems. Previously, if she got regular milk, there was green, runny poo in a few hours. Never a tummy ache though. So, any thoughts on where I should go from here? Her doc is out of the office, and the partner is a twit IMHO. Continue small trials for a few days, or something different? I would LOVE to get rid of the lactose free stuff if possible, but if not, such is life.
