How long will it be before I can leave Kayla on the floor (on a blanket laying in her boppy) and not have to worry about the other two attacking her? My son isn't too bad, he at least ASKS before touching her. Jenna is another story. She wants to be rubing her head, ect. I know it's probably the age, but Randy never bothered Jenna when she was really little, unless he was being mean to her. How long will this take to wear off?
