Sisters are about the best thing ever when it comes to playtime.
For example, Resli never hesitates to get down on the floor and share tummy time with Kennedy. Sure, she may force her to eat some gator tail, but if that's not love, then what is?
Lela, likewise, enjoys a good cuddle with Kennedy, even if the hand-holding is a bit forced.
(Pardon the nudity, the pre-shower period is particularly good for sibling interaction!)
