It struck me yesterday as I took DS2 to the aquarium then for a walk along the seafront that he was very lucky to be doing this. He'd had a few hours chilling out in the morning, taken his big brother to school, had a fun trip out, then back home for a nap.
If he had been in nursery since 12 weeks, then he wouldn't be doing half the things that he does - mother and toddlers, soft play, baby classes, singing classes, trips to the park, pre-school sessions... I know that some nurseries do these things, but it's not every day, and these are the better nurseries. Some children must spend most of their week in one room. I think this would drive DS2 mad.
I'm very lucky in not working, but this isn't a SAHM vs WOHM issue. I just think if I had to go out to work, that I would choose a childminder to care for my children rather than sending them to a nursery.
If you chose a nursery, does yours do lots of extra stuff? Do the children leave the nursery building/garden often? Why did you go with a nursery and not a CM?
