For financial reasons', I returned to work at 6 & 4 months' respectively.
There was no such thing as 'maternity leave', at the time.
Children went to daycare. They obtained 'more' of everything (except my love) than I could give them at home, especially, importantly, learning to 'socialise'. That's what they need more than ever these days', in the workforce.
My daughter, & I were discussing this yesterday, as her 7 month old daughter is starting daycare, one day a week.
Both my children grew up to be normal, well adjusted, successful persons' in their lives.
I'd noticed over the years', that 'home raised' children were more 'mamby-pamby' than mine! I'm talking '90's.
Life was different when I was a child, '50's-'60's.
But the base line is, what suits the child's parents.
It's really nobody else's business.
