To ask for advice

[UnconsideredTrifles]

I'm currently on maternity leave with DC1. I'd planned to go back to work PT, with self-employed DH also going PT (we earn similar amounts FT).

He's been building up his business and I now realise going PT will undo lots of the work he's done. My job is lovely and very family-friendly but isn't my 'dream job'. I also know we're going to want to TTC not that long after I go back, and even if I'm entitled to two lots of maternity leave I'd feel guilty taking it...

DH has suggested that I be a SAHM for a few years and it looks like a good idea. Can anyone tell me the problems with it? Any advice?
