OP, I just want to give you a couple of examples of what women routinely have to accomodate with children that, much to my frustration, men too often just don't. And you certainly dont. This is from my life in the last 6 weeks or so, and it's a snapshot based on what I can think of. But I've included things DH has had to do too.
Dh works on a shift basis. I am self employed, work mostly (but not entirely) from home and am also the main breadwinner.
This week, DD has gone to holiday camp. Yay. except, it starts later than school and is further away. Dh normally does school runs on his way to work, but due to the above, he can't. So I have. This means I've been starting work late every day this week.
DS got braces a short while ago. The only appointment we could get before September, was on a day DH was working. So I had to take him. When, on day 2, one of the hook things came off, needless to say, the only appointment for fixing it was, shock/horror, on a da DH was working... so I had to take him (I also was the one who had to call the dentist, then let the school know he'd be absent during the day).
Next week, DH has had to take an extra day off at short notice as I have to go into the office to meet a client and we have no one to take DD.
I have planned a fun "activity" for DD and her friend for Monday. This activity has been planned to allow me to work from the cafe while they do their thing. Her friend's mum will be doing something similar in exchange the following week.
My computer crashed last week. By the time I got it working again, I had lost 3 hours of work. But could I catch up that evening? No, because I had to sort the DC's dinner, take DS to his activity, and spend time with DD. Instead I got up at the crack of dawn the next day and did a few hours before they woke up.
In the last week of school, I had to go and collect DD from school because they rang to tell me she was sick.
The week before that, I had to cut two days short to take her to music and ballet exams.
None of this is great fo rme from a work perspective. I'm scrambling to fit things in, working weekends and out of hours (and yes, MUST get off MN - but I've been up since 6 am and frankly, need the break!) to try work aroudn my kids. I don't have th eoption to say, "I do as much holiday time as I can."
