The role of the well-child visit is to make sure children are healthy, developing normally, and are safe. But with all that entails it can be a little overwhelming. And the truth is, most kids turn out okay because of (and sometimes in spite of) our best efforts. So Ella's not a whiz with her fork. She will be by the time it counts. And she's a whiz at lots of other things. So your child is still sleeping in your bed. He won't be when he's 16! Enjoy it while he still wants to be with you :)
Well-checks are an important part of growing up, but if you aren't doing everything "perfectly"....don't stress! Do your best and your kids will be just fine.
