Certainly not personal to the OP, people can find themselves in very difficult positions.
Personally I don't think putting tiny DCs in child care 5 days a week is ideal for the child or it's parents.
CM, nannies and nursery workers, however good, do not interact with DCs like a parent or grandparent who truly loves the child does.
They are more detached and don't chatter away in the same way as I would to my DDs. They're not as tactile, it's just a different relationship.
Conversely they may be infinitely more patient.
I love my DDs to bits and am a SAHM, but I still sent DD2 to nursery one day a week from 18 months.
24/7 small DCs does my head in and with her sister at school I loved the peace.
She loved the company.
I think really the whole issue boils down to the fact that neither nursery or staying home with just mum is ideal.
We evolved to live in extended families with siblings aunts and cousins. Modern life can't be a perfect substitute for most DCs.
