My 5 year old DD has started saying she's scared a lot of the time, sometimes of innocuous stuff and sometimes of apparently nothing. She's always been easily scared by films (even the most saccharine Disney stuff - anything with any drama at all - we've always put it down to her being very imaginative) but it seems to be extending more and more into daily life - e.g. she's scared to go upstairs to the toilet on her own, she's scared of the cat who we've had all her life. She also seems to feel generalised anxiety, especially when she's tired - towards tea time she starts to want cuddles and says 'I'm scared' but when we ask her what she's scared of she says 'I don't know' or 'I'm thinking about the dream I had last night' (but can't tell you any details).
She also wakes reasonably often with nightmares and has had sleep disturbances (where she wakes up screaming after about an hour or two of sleep and has to be cuddled back to sleep but often doesn't remember it in the morning).
TBH I have been a bit dismissive about it until recently, thinking she was just attention seeking because we've had another DC 8 months ago (who she adores). I try to give her more attention and cuddles but of course this is challenging with a baby and can't always be managed exactly when I think it might be needed. But it is getting worse and she also quite often says she has a tummy ache, which I know can be a sign of anxiety.
Has anyone been through anything like this? Any ideas how to deal with it?
