18 Month Check Up Posted on January 20, 2017 by Allison Hite Lucas’s 18 month doctors appointment today went well. It is a sign that he is no longer a baby. He loves the rooms that our doctor has. He was so into these toys, he couldn’t even respond to me. Eventually Ruth Caldwell, FNP, came in. She is so good with Lucas. I love her. Somehow, Lucas is bigger. In every way. But the charts don’t lie. HE BIG!!!
