Do you find that non-parents are understanding of you at work? I remember before kids not exactly being sympathetic when colleagues' childcare plans fell apart and they had time off because I guess I just didn't know what it was like - I just thought they should organize themselves better. Now I'm resentful that people don't appreciate that I'm usually incredibly reliable and rarely hungover (unlike most young non-parents in my office) even if it's obvious that kids are my priority. I'm certainly less ambitious than i was pre-kids but that's partly because I've been written off as poor material because I'm a mum, I think.
