When I had my boys I stayed at home for 7 years. I was partially happy to do so but it was also better for us financially when I was with my ex because childcare would have taken my whole wage.
I got pg a month after I started work when my youngest at the time was 7. I really wanted to keep my job so made preparations to have childcare available after 6 months at home. I wasn't re-employed until DD was 12 months old.
Depending on what my mat leave entitlements are will depend on how long I stay home this time. Hopefully it's not 6 weeks lol. But I would go back anwhere from 6 months.
