My daughter is 20 months old, and she is constantly making her toys kiss. Sometimes, it's because she sees me and her father kiss. Sometimes, we'll be walking around the mall, and she'll be making her two Wonder Pet toys kiss, repeatedly. Sometimes, she'll come out of her room, pick up a toy, kiss it, and then try to make me kiss it. Is this normal? Is it okay that she seems to have a kissing obsession sometimes, or should I try to discourage it?
