To think having children does not make you less selfish

[Atthewelles]

There's a woman I work with who constantly expects everyone to fit in with her child care arrangements. Even if its part of her job to attend a late evening meeting she will insist that a colleague covers for her because 'I have kids'. She has had the last couple of Christmasses off but is insisting she is getting this one as well, even though people are meant to take turns at providing cover on 27th - 31st Dec because 'I have a young family'. She's the same with Summer holidays. The creche closes for the first fortnight in August so, as far as she's concerned, this gives her an automatic right to have these two weeks off despite the high demand from other staff.
I have just heard her discussing, with another colleague, how becoming a mother totally changes you and makes you 'much less selfish'. .
I have heard people come out with that remark before, even though some of the most selfish people I know are those with small children who expect the world to revolve around them.
AIBU to think that some people are selfish and some are not, and parenthood does not change that?

The realm of selfishness just expands. Instead of being only selfish about yourself, you become selfish about your family. So in that sense, more selfish.

But within that realm you become less selfish because having kids generally means putting their needs first. So in that sense, less selfish.
