I'm just back after my second maternity leave, and also finding the manic nature of balancing work and home life very difficult. I need to leave the house by 7.20am in order to be at my desk at 8, which allows me to leave earlier and pick them both up by 4. Mornings are absolutely chaotic and stressful. Like you, my 14 month old is usually awake at 6ish, so I can't really get ready before he is up for the day (I did try getting up at 5.30 one morning, but I just woke him up earlier so that was fun). We do as much as we can the night before, but it's the jobs that can only be done in the morning that take so much time - cajoling them into their clothes, brushing their teeth, getting some kind of food into them. And then I'm chasing my tail trying to get everything done in work, eating lunch at my desk, running home, cook a decent tea for them, do endless loads of laundry etc. It's exhausting.
I'm hoping things do indeed get easier when they are no longer babies/toddlers, though I appreciate that there are other issues then regarding wrap around child care, school holidays etc.
My DH earns twice what I earn, and does not have the flexibility to start early/finish early etc. It's hard for him to cover days when the kids are home sick etc. So it inevitably falls to me, as my job is more flexible - but it does mean that I fall behind sometimes and feel guilty about not doing enough at work. I do not feel spoiled or privileged, tbh. It's just the way our lives are. We have a mortgage that needs to be paid, and my salary helps to do that. We cannot move somewhere cheaper as our jobs do not exist outside where we currently live.
I have a lot of admiration for stay at home parents. However, if I gave up my job for a few years to stay at home, I would never get back into my field (academia). Never. I've seen it happen to quite a few women in my professional circle. Jobs are like gold dust, especially if you are tied to a particular place for family reasons. Your original job is filled immediately by someone who is very likely to stay in it till retirement, and it's very difficult to stay current and keep up professionally when you are not affiliated to an employer. So, ideas like this: Everyone's family is different and I personally put more value on being around more and not having a stressful atmosphere at home while they are so young. There is plenty of time to teach them the importance of working completely miss the point for many of women, tbh.
I took a half day today, by the way, in case you are wondering why I have time to post on mumsnet. For my twice-yearly hairdressing appointment. I don't do it at the weekend, because the weekend is family time for the most part. Work/life balance is tricky. There are no easy answers.
