oh Tegan ! I hear you!
I sometimes use a DVD or ABC kids to keep my older dd distracted if my youngest is asleep and I need a nap too, but then she doesn't get to watch any telly later etc. I haven't had any prob with TV she gets very inspired by it and after a morning session she is playing all day by herself.
I'm trying to focus on quality time rather than incidental time although that is really important too. My mum worked part-time (as do I) and I really liked the little rituals like shopping together and a milkshake on saturdays, going to the beach after school every tuesday afternoon etc. I also like mum just being in the kitchen and being 'around'.
That said, my DH and I are trying to make sure we spend lots of time with the girls on the weekend focussed more on what they enjoy than what we do!
I thought it was an interesting topic, but most mums at bellybelly tend towards more attachment/gentle parenting styles so probably spend heaps of time with their kids.
