At the end of the day, research changes every so often. Wean at four months / wean at six months. Put to sleep on front / Put to sleep on back. Stay at home / Go to work.
I was het up about this yesterday, possibly due to it's close to my time to return to work. But I think I'm just going to put it out of my mind. I know that when I get home from work with my DD, I will give her all the love and attention I can. Yes she'll be spending some time in nursery, or with a childminder, whatever, but she'll be home with her mummy and daddy at the end of the day, who wont be stressed out by money (not a sahp trait, but it would be our situation), who wont be stressed out because we never see one another.
We're all trying to bring up our kids in the best way we know how, and as somebody pointed out long ago on this thread, we should all support one another rather than critising the "other way". I think that is the one downfall of motherhood (and many mumsnet threads), that we get split into camps. SAHP Vs Working / Breast Vs Bottle / Early Weaning Vs Late Weaning / Routine Vs Demand etc etc
I dont think that being a sahp is a bad thing, I think those who can do it (financially and mentally) are very lucky. I just hate the idea that people think that because I will go to work, I love my child even an smidge less than they love theirs.
