Your husband is possibly bullshitting you about how tight your finances are. We are a two income family (I work part time, DS who is 9months will be going to nursery three days a week. Hope it doesn't fuck him up too much
) and our combined income is a bit less than what your DH is earning. We are comfortable; we don't have money to chuck out the window, but we can afford nice things like a spontaneous night out, or new clothes if we fancy them etc. And we manage to have a three bed house, in a middle income area (prob more expensive than the north east) and substantial savings. I'm not saying this as a stealth boast, just pointing out that your income should be more than enough to eithe rlive in a bigger place or have a cleaner or hire some childcare. The fact that you don't have a clue about the finances worries me. DH does 'deal' with the finances in our relationship, but we discuss them (ie, when it's time to renew the insurance, or make a big payment etc) regularly, and I'm completely in the picture about how much money we have and where it is going, and I have access to it (although we do have seperate accounts, which some people are horrified by). With regard to the tumble drier. Use it in secret for a few weeks and see if he even notices.
As far as the whinging; there are loads of brilliant suggestions on this thread for how to entertain your kids (I will be stealing some of them). DS is the same age as your youngest, and it is a hard hard age. But they whinge at this age because they need something. I just try and distract him; start a new activity, swing him round the room, go out for a walk etc, and if the whinging continues, I put him down for a nap because it generally means he is tired. 9pm bedtime is mad, DS would be a hysterical wreck if we kept him up that late. Bath and bed by 7 here, and no napping after about half 3.
If you want to continue your business (and given how controlling your husband is, I would too), then you need to get some help with the kids. There is a reason people don't generally take their kids with them to work.
And lastly, your husband sounds like an arse. He doesn't do 'more than most fathers'. Most husband and father raise their kids and support their wives, because most of them are decent human beings. He's a whiney man child who needs to grow the fuck up.
