I have a 2yr old ds and a 6 month old dd. I split up with their father when I was pregnant, he was having supervised contact with ds but since dd has come along it started to get less often and eventually stopped. He's held dd about 3 times.
Since she was a few weeks old, if anyone even looks in dd's direction who isn't me she has a meltdown until I pick her up, if anyone speaks to her, she has a meltdown... and if anyone tries to hold her she goes absolutely mad. I guessed this was because she has only really known me.
I thought by 6 months she would of grown out of this but there's no signs of it yet. It's getting exhausting.
I'm unable to leave her with anyone, even for the shortest amount of time 
Anyone have any advice?
