They're jealous jealous jealous!!! 
Just enjoy your stay at home mommage! And ignore the haters. 
(not sure mommage is a word!) 
I have to work and I am soooo jealous of sahm's. It must be great to stay at home with your kids.
(Not meant as a put down btw. If you can stay home, then do.) 
Having said that, if mothers decide to go back part time (or full time) as they function better as a human being when they are at their job, (or they need the money,) then that's fine too! Whatever makes you happy, just do it, and fucking bollocks to anyone who comments! As has been said; if everyone is happy with the situation, children of working moms will fare just as well as children of sahm's.
It's actually quite good for them to go to childminders and nurseries at a young age, as it socialises them and makes them mix with their peers (not just siblings and cousins etc.) Having said that, it is of course possible to do this when you are a sahm; you can take them to playgroups and suchlike, so there is no right or wrong!
Why people feel the need to question and bash and berate peoples life choices just baffles me to fuckery. My lovely cousin (who I am close to and is like a sister to me,) has 2 kids (primary age) and she works 2.5 days a week. (She works for the Civil service and worked full time for 10 years before going part time after her first child.)
She gets asked CONSTANTLY by people at work, (a couple of women AND a couple of men, including her manager/boss,) when she is going full time again. They say 'your kids are old enough now for you to go full time, they don't need you.' (FFS, your kids ALWAYS need you! Such a cunty comment!) And this has been going on (on and off) for about 7-8 years.
And yeah, so she is always bashed. She is thinking of moving on, to somewhere else - and working 2 days a week, where she (hopefully) won't get nagged to go full time. She can afford to work part time, her kids love her being around quite a lot, and her husband loves her being home a lot too. Everyone is happy with it. So why don't people just fuck off?
