Jac has a VERY! small belly

We have been giving Jac Benecalorie for over a month now. I can't tell if he has gained weight but he has a very small belly. Katie and I noticed it and Daddy noticied it tonight. I think it is a good thing, if it means he has a little, tiny bit of fat on him! We will be seeing his endo shortly and I will ask him about it.
