Midnight meeting

When I change Bean's diaper in the middle of the night, she gets so excited to see the mobile over her changing table that she kicks her legs and does her practice "laugh". She will lay there happily talking to her animals for quite some time, as if she has really missed them while she's been asleep and has important things to discuss. Daddy says Playing in the Middle of the Night is not allowed, but getting your diaper changed doesn't count as playing, right?
