I probably am BU, but I hear a lot of mums saying how their (sometimes newborn) babies are being 'naughty' by crying a lot, waking in the night etc.
Maybe I'm just being oversensitive because I would love to have my little girls at home waking all hours of the night for me to look after them, not a doctor!
It just makes me feel a bit funny, and most of the times I've heard it it's not been meant in an endearing way, more of a way that the baby is inconveniencing them a lot. :(
