Cam is still just barely starting to interact with “little sister”. Today he helped with Demi’s tummy time. He held the toy out and shook it and she turned her head toward it. Then, after a few minutes of trying to hold her head up, she got frustrated and asked Cam to find her “baba”. He ran and got it, put it in her mouth and she was instantly soothed. When I told him he made her happy, he got excited and gave me a kiss. Small moment, but very sweet.
