I'm a long way from being OCD about housework but I've come a long way since my early twenties. We have a one month old and a three year old.
Systems are of critical importance, our task this evening is to sit down together and reevaluate who does what - somethings which I've done since we had our toddler I cannot do with a newborn as well (like washing up) but the laundry which my DH used to do I can do with my mini helper. However its becoming clear that I need DH to get the toddler up and breakfasted and then hand her to me (feeding baby in bed usually) while he makes lunches and gets the kitchwn shipshape. Since I was six months pregnant he has done all the cooking and increasingly does the weekly shop as well.
Being organised beforehand again critical. We weren't. We've often said has we moved to this house prior to having our first DD we would all be happier, as it is its part renovated but the garden isn't safe for DD1 to play out on her own yet. My office in our last house has been set up in an inbetween lobby and all paperwork is just dumped there and it spoils the whole of the downstairs. We've booked a carpenter to build storage but cash flow is a slight issue at the moment.
We also have a lounge and a playroom. As long as mess (aka children) are never allowed in the lounge we always have somewhere clean and tidy, and as and when I get five minutes I target those areas where sticky fingers and crumbs end up.
Parnsipcake list is one to remember, my DD1 rarelu vomited, but DD2 projectile vomits several times a day requiring sofa cusions, throws, my clothes and her clothes all to be changed and washed. I have a set of indoor clothes and get changed just before going out. Staying on top of the laundry therefore is my priority after ensuring both children are fed.
Horry's mention of the fourth trimester however certainly is true in this house. And as many posters have said it does depend on your baby. DD1 cried 24/7 and rarely slept, it was a good day if I ate lunch and a great one if I got dressed and got out of the house. She was also very poorly as a baby. Some evenings we only ate because someone had kindly dropped in food. This time round DD2 lets me get on with things, she is mostly very good natured.
I don't iron though. Nothing at all.
