It's the tone that comes through marynary
Looking after my own children was a huge priority for me, but it isn't for everyone.
It reads like anyone who doesn't look after their own children puts them as a low priority. One comment on its own might be accidently badly put but whiteline has made quite a number of comments that come over as "well I never let my children cry, if you do then they're not your priority, all you need to do is get up at 5am and work after they've gone to bed, I gave up my career to do that, how great am I!"
As said, one comment on its own is rarely much. But the sum total here is not exactly friendly. Especially as most reasonable people who kind of have a bad day posting tend to realise after they've been told by several different people and say 'oops, sorry!"
I don't think it's worth getting worked up about, but Mumsnetters do like a good bunfight =)
the only real pity is that the OP, who was unsure what was the best thing to do in the first place, was made even more unsure by 3-4 posters who haven't so much said 'well it's not for me" but taken this smug and sometimes highly critical tone - one poster called her selfish for wanting an hour in the gym :/
