We started doing signs for I LOVE YOU several months ago at bedtime and Paxton quickly caught on. He started doing it back to us at bedtime and now he does it whenever one of us leaves him (at church, with a babysitter, at bedtime, etc.). It is one of my favorite things he does! It is so sweet. He does it to all four of us and at nap and bedtime, he will not go to bed unless he hugs everyone and signs I love you!
