I don't currently work outside the home, although all my children are now at school. I did work outside the home, on a self employed basis when my DS3 who has Downs was aged 1-4. I arranged my own hours so they fit in with my older two sons school hours.
My son went to a 'daycare' type nursery until he was 2, then a mainstream nursey school (although it wasn't a 'day are' type nursery, they offered 9.30 until 12 then 1-3.30 sessions per day, plus a lunch club, so DS3 went there from 9.30 until 3.30 for three days, then 9.30 until 1 the other two days. I also had a child minder for a while whilst waiting for all the nursery sessions I wanted to become available.
I was a single parent at the time, plus had my own horses, so I( felt I had to work, and I had no family nearby to help at all.
Yes, we sometimes had takeaways, but he children had a 'proper' meal at school ,which helped, as it meant I didn't have to bother too much if I didn't want to, and if I really couldn't be bothered they'd have something like pasta with butter and cheese, or sausage and chips etc. They ate plenty of fruit, so I didn't feel too guilty. I was tired most of the time, and yes, sometimes the housework got on top of me, but I only had myself to please and so it didn't really matter.
Now I am re-married, hence not working, but I am thinking about looking for part-time work in the New year. I struggle sometimes now, so wonder how I'll manage, but I always say I am never tired until I sit down, I'm fine if I keep busy, and I have to admit, I felt better when working.
