"If parenthood changes your life, and I agree it does, then why is it that (on the whole) it doesn't appear to change the life of men. Are they not parents too?" I share nooka's thoughts.
When dd was born, I was the main wage earner and dh was on a temp contract. I had to go back to work to pay the mortgage and was mostly happy to do so. DH could not have stayed home either as he was just starting a career change after taking a late degree. It would have killed his career off at that point. (He is 11 years older than me).
7 years on, dh's career has come on in leaps and bounds, we moved abroad to facilitate a promotion - and I hope upon hope that he will continue to do well - he only has 11 years to go before he is 65.
I still have a good job, but I don't have a GREAT one. I don't have the job that I think I should have - mainly because DH travels so much and there is NO WAY I can take on the same level of responsibility and not hire live in care for dd. I don't want to do that. I want to be home every night after school. That is my choice. DH also does his share in the house/entertaining dd. Generally it works quite well and I am happy that DH earns the cash and bumps up his pension as he will be retiring a long time before me.
But it does piss me off a little that DH can just makes plans and disappear at the drop of a hat, based on the assumption that I will pick up the slack. That goes for work trips, occasional visits to the pub after work, team building and the like. I have to fit round him and cancel things if required. I can never, ever just decide to pop for a drink after work as the school run is normally done by me. I have to make "arrangements".
Also DH never gives any thought to all the "stuff" that goes on in the background for dd - dinner money, school trips, new clothes, presents for parties. He would do it if I asked him - but it would never occur to him otherwise.
He is generally a hands-on dad and dd adores him, but I think that being a "dad" seems to be somehow different from being a "mum" - but is it the job, biology or the Patriarchy, or a combination of all 3. I have no idea.
