She is a perfectly nice woman really, single and no kids (no idea if this is through choice or not). I try very hard not to be a baby bore at work and only mention DS if someone asks after him. She and I chat quite a lot, she'll ask me how I am (and vice versa), and if I dare to mention that I'm a bit tired or have had a hard night with DS she'll make a sort of 'aunty knows best' face (IYSWIM!) and say, 'oh well, it is self inflicted after all', in the sort of jolly/disapproving tone you'd use to someone hungover. Well, yes, I did choose to have a child (although she doesn't actually know that!!), but I wouldn't describe a sleepless night caused by DS crying because he is unwell/teething as 'self-inflicted'.
She also seems to think I have it easy as have more time off than her - but again if I mention that this 'time off' is largely spent caring for a small child, I get the same comments. This is starting to wind me up somewhat!
Sorry if you think IABU, but have to vent on here so I don't have a go at her in RL as she is quite sweet normally!
