Hi Noggin
I have 3 children but I only work 2 days a week. We have no family living near us so it's just me and OH that can deal with any childcare. I will be going back up to 3 days but not until September.
My eldest is in school (and after-school club) and the other 2 in a private nursery. We could in theory do this every day so I could work full time but I find the kids are so exhausted by Wed (I work on Mon and Tues) - but then they are out of the house from 8am to almost 6pm so they are very long days for little ones.
My other problem with working full time would be fitting in all the household chores but if you are organised, I think you could do it. I have so much laundry to do, that is the biggest chore. When I go up to 3 days I am seriously thinking of having a cleaner - just to come an hour a week to clean the bathrooms (1 bathroom, 1 ensuite and 1 downstairs W/C - the upstairs ones very rarely get cleaned at the moment!) and the kitchen floor.
The other thing to consider is illness - it is very hard for us when the kids can't go to nursery - we either have to take holiday or I sometimes work from home, which then involves working really late in the evening after the kids are in bed.
Interested to see other replies and people's views. Good luck with it, I'm sure with good time management and organisation it can be done!
