Hi - I feel for you op, and I feel strangely better for reading all the replies from people who share similar feelings - I thought it was just me that was struggling to cope. I've got four dcs - ages 6,4,2 and 6 months. At the moment I'm on maternity leave, so I've got them all (well, I've got them all with me for these two weeks because its the Easter hols) next week dd will be back at school and I'll be back to the relentless dragging the others along on the school run with me.
Dh comes through the door and manys the time I've been sitting at the bottom of the stairs holding the baby, ready to chuck it at him, or will instantly start ranting about all the things I've had to deal with. There is no question he is tired, I'm tired, its all a disaster!! We tend to battle on - try to get tea for everyone sorted asap, and bath-time affords a little bit of time for dh to get changed out of work clothes at least, and we catch up with each other while chucking children in and out of the bath/shower. We like them all to be in bed by 7pm latest, then we usually don't speak for another hour and a half. He will be checking emails/facebook etc, I will be bf upstairs, and MN... we both just need some space I suppose, then its on with the jobs - loading dishwasher, making packed lunches, ironing, dealing with the laundry, wiping down kitchen, tidying playroom etc. Sometimes we are working until 10pm. The thing I realise is that the competitive tiredness thing is pointless, and exhausting in itself. You are a team - one team member works in a different place, but the team works more efficiently together, so get on with the stuff together as best you can, then when the children are asleep, try to re-charge your batteries for the following day.
I've just asked my dh about this - how could we have a 'break'. He said an evening off would be no use to him because hes so knackered when he comes in from work it would be pointless trying to go out. I said that it wouldn't be an evening off for me, because I'd still have to do my share of the bath-time routine, and then I'd be dashing about trying to do my other 'jobs' either before going out, or when I got back, so its more effort... We have this discussion constantly because even on holiday there is no break - in fact sometimes we have to work harder because we're in an unfamiliar place and don't have the same comforting (?!?!) routine.
For everyone saying that the only way dh will learn how difficult it is is to leave him with the dcs, it doesn't exactly work like that. When I'm not on maternity leave I work one day a week and dh has the dcs. I find that he has a really enjoyable day with them - lots of fun, out to the park or to visit his parents etc, and I come home and will catch up with the laundry/shopping/cleaning etc. Same if I go out over the weekend, he prioritises having fun with the children (which is no bad thing - which is why its good we're a team I suppose) whereas I have to get my 'jobs' done first before we get out to toddler groups etc. If you let dh have them, he may very well do things his own way and not get a full understanding of why you find it so hard, because compared to being at work he might find it quite fun (but the novelty would wear off if he was doing it full-time I'm sure!) - but would it matter if it gave you a break?
Friends of ours have a lie-in each over the weekend, i.e. one parent gets up and does breakfast with the dc while the other lies in bed - would that be a start? We prefer to keep sharing the jobs whilst we are both home, as it makes it easier and quicker. Maybe your dh needs to up his game and get involved as soon as he walks in rather than have a break. No wonder you want a break if you can see him having one - I know when I'm working I'm straight back into it and then some when I walk through the door... hmmm... not sure I'm helping ...
