Carter 15 months

Carter had his 15 month appointment last week. So frustrating because he hasn't gained much weight and doesn't technically walk yet. He has been off and on sick the last couple months along with teething so his appetite has decreased. I got so annoyed at the dr asking me over and over if I was concerned that he wasn't walking yet. He wants me to bring him back in a month to see if he gets better and gains some weight. His ear, nose and throat were all a little red and irritated. Hoping he gets better so I won't have to take him in again.
