My dd aged 4 years has been sleeping with me and dh on and off for the last six months. She goes to sleep fine in her room and then appears at about 1am and climbs into bed with us. When I ask her why she says that she feels like a cuddle. Should we try to persuade her not to? She has always been a good sleeper and she doesn't really disturb us but I don't want to build up any problems in the future.
