Well, I'm a Childminder so that I can afford to be a stay at home mum and TBH it's not much different as I treat my mindees pretty much like my own and get on with things as I would if I didn't have them. I wouldn't do long jobs such as the ironing or hoovering whilst I'm working but the odd bit of housework such as loading the washing machine, hanging out the washing and doing the dishes, yes, I do and if you're smart you can find a way to include the children so that they are having fun, earning a new skill and getting the job done quicker too.
I make sure that I have a couple of good, close friends who also have children and get them to pop over to my house so that the kids can play together and we can have a good natter because my God, you can get lonely and miss adult company!
I also arrange with these friends, outings to the local swimming pool, soft play, lunch in a cafe, walks to nature parks to feed ducks, library, shop, mother and toddler groups etc and I try to get out for a morning walk and an afternoon walk.
I try to restrict telly to 2x15min slots in the day and try and go with the flow as much as possible. Get down on the floor and muck around, build towers and have fun knocking them down, play lions and hide under the table, make a den, pretend to imitate different animals, dance around to music, sing songs, collect musical instruments from charity/car boot sales and have fun creating a band, read stories, collect things, dress up, fill up a paddlng pool with warm water in an area in the house where it's ok to get it wet and surround with towels then have a 'pool party!', pop to your local 'Petsmart' to see all the different pets for free, visit local attractions and buy a season ticket, get involved with helping the community, attend village fairs.
Try and meet up with other adults at least 3 times a week.
Try and sync naptimes so that you can grab an hour to yourself.
Don't feel guilty if you havn't done much with the kids one day, a bit of boredom for them is great for their imagination and also teaches them self-sufficiency but make sure you arrange some fun for the next day.
