Am really at the end of my tether.
DD has, in the last three weeks, starting having meltdowns - with me only. She never cries with her cm or with dh. One morning I woke her up and she cried - proper snot, drool, etc, for 40 mins before settling down to have her breakfast (by which time we were really rushing). Another evening she fell asleep in the car on our way home from cm and when I woke her up on arrival we had the same thing. She sat on my lap for 40 mins crying hysterically.
Now she has started doing it more regularly and usually triggered by something that she doesn't like, but not always. She is inconsolable and I can't do anything until she calms down. I try talking to her and she sobs back at me. She seems really sad and these don't seem to be tantrums. She clings to me, asks for her dummy (a rare thing) and her comfort blanket. I thought that it was tiredness/changing weather etc, but the last four evenings she has done this, before snapping out of it, eating a huge supper and then refusing to go to sleep. 
I have been on my own for the last four days and every day is worse and worse. I am at the end of my tether and usually end up crying too (made worse by the fact that I am 23wks pregnant, hormonal and permanently exhausted and possibly a little depressed).
The other issue is fear of the bath. DD went through a bad patch at 10 months old which was resolved by me bathing with her for a few nights. This came back over the summer - we had moved house and have no bath, and she is terrified of the shower so we put her back in the baby bath. She went through phases this summer of being terrified. These phases have gradually got longer and worse. For the last 2.5 months she refuses to get in the bath (cue meltdowns, see above). We can just about sponge her down but have reduced this to twice a week as it's just too stressful for all of us.
We have tried - bathing her with friends (she screamed and cried, upsetting her friends). Paddling pool outside - fine as long as she doesn't have to get into it. I think the original fear came from the shower/having water in her eyes, which both DH and MIL insisted on, despite my objections. I know it is normal for toddlers to have a fear of the bath at one stage or another, but cm and others have said they have never seen it so bad.
Any help or suggestions greatly appreciated...
