I feel the same, said to dh yesterday I want to go back and do it all again but not necessarily have any more children.
Mw's and hv's were closed today so couldn't have anyone to check my hip/thigh but have shown dh where the pain is coming from (he was a sports person) and he told me it's my femur, I had some voltarol and a hot bath and have a heat patch on now which seems to have helped.
My mum has offered to have dd1 for some of the day tomorrow but I don't know whether I should just brave it and have them both on my own as I'll have to get used to it sooner or later.
I have put on around a stone and a half the half was put on after the birth so am starting to eat healthily from tomorrow.
