Ugh, if she hates parenting so much, why is she so dead set on having another child?!
I get frustrated like this with my nephews when I've been looking after them for several hours and they're getting a bit awkward and I'm getting a bit over it. I know I'd be the same (only more so) if I had my own, so I've decided not to have children. It was an easy decision, despite the fact that most of my friends and relatives have children of their own (as in, I always knew having children would be an option/choice/decision, not just "it's what you do" like Lily).
Christ she makes me incoherent - sorry for the terribly rambly post!
