Hows this!
When Emily is tired I ask her if she wants to go to bed...she looks at me and says "Buh" and runs of to her cot (as long as I go with her) and wants to get in to go to sleep! Sometimes she'll go in there on her own and stand at her cot and sook to get in!
Isn't that great! I hope she does this for a long time!
