Sorry, this may be a bit long, I'm trying not to drip feed information.
DS is 20 months. I work FT, DH is a SAHD. DS is in nursery two days a week: on those days DH catches up on sleep, does laundry, fixes computer, generally potters about the house.
DS is still a pretty bad sleeper (or rather a bad teether: every time we think he's started sleeping through, he starts cutting another tooth and is up in the night wailing and wanting Calpol, or he brings home yet another cold from nursery and wakes up in the night coughing). DH does all the night wakings because DS only wants him at night. This pattern started when I stopped doing night breastfeeds, and we've never had the energy to try to get DS to accept that he might get either of us at night, so the deal is that I do all the early mornings. So on nursery days, I drop DS off on my way to work and DH can sleep in uninterrupted, on other work mornings I do nappy change, dress him and do breakfast and then hand over to DH, and at weekends I have him till DH gets up.
This is not a thread about DH not pulling his weight domestically. Housework is split pretty fairly, I think, and when I'm here the childcare is split more or less 50-50.
I am knackered. Apart from an hour or two each evening, I'm either working, looking after DS or doing housework, and it feels relentless. I do meet friends once a month or so, but I try to do that on work nights so it doesn't get in the way of family stuff at weekends. I would kill for a bit of time on my own at home, although I'd settle for being able to go out alone for an hour or two. I don't think DH would mind if I took a bit of time to do an exercise class or something at the weekend - this is all about me feeling guilty for being generally a crap mum and a crap wife and trying at least to compensate a bit by being a present one.
What would other people do? I can't commit to anything regular on a work night as I quite often have to work late, or have to travel so I get home very late, so weekends are the only practical time to do anything for me.
