My daughter had always been nervous and worries about things more then her siblings. She started getting so stressed about sleeping on her own we were spending more time every evening trying to get her back to sleep we ended up letting her sleep in our bed as we both work and need to be up early. I assumed that she will grow out of this, but I've also noticed she really worries about any film which has a bad person in it, even if she's seen it before and knows it will all be ok. For example she loves Moana and frozen but refuses to watch them. She only watched cartoons with no bad people like hey dugee
But the last couple of weeks before going to sleep she's asks me a couple of times if the doors and windows are shut and locked. Especially if her dad is not home, tonight he popped out to B&Q as I was putting her to bed and she was really stressed. She had two older siblings who are not like this at all, should I be worried or concerned about her ?
