I've just hit the knackered bit and am feeling v sorry for myself. Just put DD out in the garden for a runaround while I watched from indoors - I just couldn't raise the energy to go with her. Feel really bad about it she's only 15mo. I think it's going to get worse before it gets better - last time was dire and I didn't have a toddler then.
So how did you get through it? I just have to grit my teeth and get on with it don't I ...
