Apparently, the thought of doing it makes her toes curl, she informed me recently.
Now, before anyone flames her, I have to say she is a genuine, lovely person, but is not maternal at all and has no children. She hadn't really thought about it in any depth.
I was quite shocked and said so, but we had a general (goodnatured) conversation about breastfeeding (I bf my three for a fair while) and thought no more of it.
Anyway, she went home and had a discussion with her mum about it, mum told her basically she was talking rot, lol. (good ole mum).
Colleague is late 50s, and she really is lovely.
