I guess she could be trying to push the boundaries a bit, I'm not sure.

The other thing is that perhaps she has had a bad dream? Do you think that's a possibility? Perhaps something has frightened her a bit, or freaked her out. The other thing is that if she's teething and they've been hurting her, then perhaps she's associating going to bed with pain (most people if they have a toothache or anything that hurts find going to bed can be quite hard as the pain seems worse - I guess when you're in bed you have no other distraction from the pain IYKWIM?).

Perhaps you could try leaving a dim light on to see if that helps, or giving her a toy of some description that she could cuddle up to of a night time?

Jacob doesn't normally protest at going to bed and will usually chat/sing himself to sleep. If he doesn't, or starts to become upset, we go in to him and settle him (it can take a long time sometimes!). Sometimes we need to do only a little settling and other times, he will start to scream again as soon as we leave the room (like he did tonight - he's only been asleep for not even half an hour!).

I don't think I've helped any....eeek! Good luck!
