Its a hard decision, but definately not selfish to want to spend time with your bub.

I know in my case, I would not have been able to go back to full time work when she was 8 weeks old for a few reasons. I had a rough 2nd stage labour and did some nasty damage, resulting in quite a bit of pain for around 3 months. I work in an office job, so for me, the thought of having to sit on my still rather sore bum all day was not sounding appealing. Claire is also breastfed, and only recently started sleeping more than 2 hours at a time. I know that with her waking as frequently as she was, I wouldnt have been able to work full time.

8 weeks, and even 12 weeks went soooo quickly. She was still a little blob at 12 weeks and I cant imagine having left her then. I still havent gone back, but thats more because I'm being stuffed around by my employer. Having said that I have a friend who went back to work full time when her baby was 5 weeks old. Bub was in day care full time.

Can you do up a budget and see how long you might be able to spend at home with your bub?
Would you be able to go back to work part time instead?
I'm not sure what type of work you do but would there be the chance of working from home?
