blueshoes i'm a SAHM and your comments make me feel about being a SAHM, so I feel in a way i have to defend myself a bit! No dd doesn't get full on 1-1 attention from me because of housework (and sitting on here!) but actually I think she gains a lot from that too - being an only child, and me a single mum, there was always a risk that she would never learn that other people have needs, that she isn't the centre of the universe and can't expect to get everything she wants as and when she wants it. I actually see it as a positive thing (or try to, most of the time I feel guilty), a learning experience for her. She has developed from being an extremely clingy baby to an independent, content little toddler, able to amuse herself as well as play happily with me and with friends that we meet up with. I have made a conscious effort to make sure she learns the concept of having to wait for things, taking turns when playing with things, etc. So the way you describe a lo's life with a SAHM isn't actually as negative as you put it, iykwim. (I know you weren't intending to be completely negative, but that's the way it came across.)
But I also have to agree, if there was free nursery care for dd now (she is 2.6, I am looking forward to when she gets her place at 3 yo) I would be very happy as I agree she would benefit so much from it now - part time that is. She can't possibly get everything she needs from me and would so benefit from all those artsy crafty and physical stuff they do at nursery, as well as socialising with children her own age.
(I do baulk however at the idea of putting a 6 month old in nursery, esp full time. Couldn't possibly have done that with my dd given how clingy she was, how often she bf etc! But I know babies are so different, i looked after a friend's baby from 6-12 months old who was completely happy wherever he was, whoever he was with!)
