My DD is at home with me full time and I love it - I put a lot of effort into interacting with her and thinking of fun things for her to do. She also does plenty of toddler groups etc so she meets others.
Does anyone know what research says about the benefits of nursery for a child with a SAHP? I guess going from being home with me all day now (19mo) to full time school at 4.5 would be a shock, but I'm not sure how much she'd benefit from nursery / pre-school in the meantime and how much she benefits from one to one interaction with me instead.
