Backstory: Been with DP for 2 years, expecting a son in Autumn. DP has a DD (6) and I have a DD (6) and DS (5). The kids get on really well together. DSD has always enthusiastically referred to my kids as her 'sis' and 'little bruv'. All kids excited for the new baby, enjoy talking to my tummy, discussing what he will look like, etc.
DP is currently at the final stages of his divorce, and it has been very messy to say the least (Cafcass involvement; now LA involvement). DSD has developed behavioural issues (become highly competitive, tantruming, shouting a lot). Sometimes she hits her dad and says "You love [DD and DS] more than me". She picks fights A LOT. And now suddenly she's started saying "We are not a proper family and we never will be; Even marriage will not make us a family".
Where is all this coming from?
Is there anything we can do for this disturbed little girl? We've started taking her to a private child psychologist as the NHS waiting list is at least 8 weeks.
I admit, I've started avoiding DSD where possible as I feel very anxious when she's around. She recently came up to me and asked "Is the baby dead yet?"
