NC and sorry if this is a bit rambling (bit upset and baby is climbing on me)
DD (nearly 8 months) can't really be soothed by DP, he tries and I try to let him try but she screams so hard she's made her self sick a lot or she causes bruising on her skin where she's burst blood vessels 
I've only been away from her a handful of times, we've worked out she's better with DP outside of the home so when I've gone to an exercise class (not close to home) he's come out too to limit the time apart partly if she gets inconsolably upset and partly because she still feeds hourly and she doesn't take bottles well.
This morning he took her because I was exhausted and she was fine with him but when I passed her over after sitting around with them because she was crawling all over me and hurting me she just screamed and screamed, he tried to take her out of the room and calm her down but she just wouldn't. Offered to take her back after a while but he said she had to be able to calm down with someone other than me so I went back to the living room and had a little cry. After a bit more trying to sooth her her brought her to me, she has burst blood vessels again and he feels awful.
She's just so clingy, she'll scream and sob if I leave the room sometimes, or even walk across the room. DP can calm her down if she's bumped her head or something I think but quite often she just wants me and won't calm down till I hold her.
It's upsetting for DP because he feels like he's doing something wrong, hence been on together recently but in the passed he's barely been able to hold her without her crying. It's worrying me because at some point I need to go back to work and I can't have her getting that upset several days a week, what if I just get called to come get her because they can't look after her?
Help, experience, sympathies?
