I have DS nearly 5 and 17 month old twins(boys too). Twins both now up on feet in the last few weeks, which has added to chaos. We moved house from Birmingham to Cornwall this March and nearest family is 2 hours away.
Amazes me how I can plan what I want to do, and yet (like today) it's 10.00 and I'm still in my PJs, having still not made it into the shower. But the washing up has been done! 4 weeks before twins were born I was working managing people, organising stuff! To go from full-time work to full-time parenting was a shock (4 years of uni for this!). Sometimes it is frustrating that the kids dictate what we do and the house needs a good clean. DH is self-employed and works from home, which is a massive bonus although for the last couple of months he's been working for a company who seem to work 12+ hour days. He hasn't helped bath the boys for....can't remember last time.
Anyway, I've tried to add structure. Toys are boxed up so kids have a limited amount out at any one time (I change them over every so often) this limits some mess and DS1 is able to help pack toys away (boxes were labled with pictures of what went inside although twins seem to have peeled off most of these). Twins still have a good nap in the daytime which helps. With pre-school for DS1 twice a week, toddler group for twins once a week and storytime at our local library I have two days with nothing "planned" to do whatever we like. I've got discount cards or membership for some of our favourite "attractions" to try to make going out cheaper and I take picnics with us. I do big online supermarket shop at least every fortnight which removes one stress. It's taken a while to get to this stage - but the thing I miss about work most is the social interaction with other adults so i make sure I get to what I can just to talk to other mums! Especially as my little social network was ruined when we moved and i have to build that up again. Advantage (?) of twins - complete strangers will always approach you to ask about them!
At the end of the day, we used to pay a fortune in nursery fees for DS1 while we both worked full-time. Now at least I get the pleasure of influencing the boys early years. And, they're all healthy and happy.
DS1 starts school in September. Don't know where his first five years have gone. So, however hard it gets, and however cut off from reality I sometimes feel, it doesn't last long so I'm trying to enjoy it all.
