Anyone got any views of when to make the jump to the big bed. My little one is 2.5 and we've got her used to a cover and read all the books to get her excited about it but there doesn't seem to be the same clear lead from her as to when she's ready like there was with potty training?? I'd like it to happen as she's been dry at night for a month and think being able to go to the loo herself at night and early morning would empower her and (as a useful aside) stop her using calling for a wee wee as a stalling/attention tactic ... views please?!
