I do it brette.
I went freelance when ds1 was 6 months old and have remained freelance, working from home since and I've now got 3 ds's aged 4, 2 and 5 months!
When ds1 was little it was easy as he was a very contented baby so I worked while he played next to me, when he napped and also in the evenings.
I've had to adjust as each babe came along so have worked more on evenings and weekends which is not ideal but means I've really had no great childcare costs and have been fortunate enough to look after all 3 of them myself (very important to me personally) and 'keep my hand in' and earn money.
Now ds1 is in pre-school 4 mornings a week, ds2 goes 2 mornings a week so those mornings I can pretty much work while ds3 sleeps.
It is certainly not easy - it's exhausting but whether you do it will all depend on your priorities I guess.
I couldn't face daycare for my kids and wanted to look after them myself - that was my number one priority and I've worked round it and made sacrifices elsewhere to be able to do it.
Don't forget, although it's a way off yet, once your kids are at school it's the most ideal position to be in - you can do drop off and pick up (again, I hate the idea of after school clubs for them), after school activities etc and work/sort out house/shop during the day!
Good luck!
