Jenna I don't think anyone would disagree that the very specific situation you describe where a family are financially stable with no need for the mother to go back to work but the mother choses to and as a result the babies are in nursery from a very very young age and only see their mother for one hour a day is less than ideal....however, it does not automatically mean that child can't grow up to be a well rounded and adjusted individual.
You say you had the far from perfect childhood yet from what I can tell you seem to think you are living the perfect life so nothing has gone wrong for you....? Is that not case in point? Or are you living the way you do because you feel bitter and think this is what you have to do (that is a genuine question).
As this thread has established things are never as black and white as the situation you describe, there are countless reasons why women go back to work listed throughout this thread.
All these threads do is stir up bad feeling and competitiveness between SAHM and WAHM and there is no need for people to justify the choices they make.
I work, both my children went to nursery from a relatively young age (8 months and 1 year) but I bend over backwards to organise my life so they don't miss out....I go to work early so I can be back in time to listen to them read in the evenings, do their homework with them, cook them meals. I clean the house when they are in bed. I organise my life so my children do come first in every way possible.
I personally tend to find that when someone is so blantantly looking for approval and confirmation that what they are doing is best it is an indication that they aren't secure in the choices they have made and need the reassurance that they have done the right thing.
I think it would be safe to say that everyone on MN loves their children and does what it best for them in their own way, we are all different and make different choices can we not just live and let live?
