DC1 went from 7mths. Full time.
DC2 went from 13mths 2.5 days per week.
I was very happy with the nursery - it is very well regarded locally and people refer to it as XXXXX's place rather than its name because the owner/manager has been there for years and is well known in the community - one of those formidable but warm types.
DC1 has always been very independent - would insist on feeding himself, toilet trained really early, famous words "I do it, I do it" about EVERYTHING! I think nursery was abolutely the right environment for him and I see him now developing into a really sound, sensible young man.
DC2 has always needed more. We joke even the second he was born he looked around eyes wide open then as soon as he was cuddled into me he closed them again and went back to sleep. He's 8 now and still a cuddler, still needs tons of affection/comfort/security. Looking back, it was probably good for him to go to nursery from so young as I think he may have become too "clingy" - that's not the right word. Full time, for him, might have been too much of a stretch though. Or it might have been good for him. I don't know!
What I can say is both boys are well adjusted, full of love, and content. I do credit that particular nurery with a lot - they both have beautiful manners not from me and I didn't feel guilty about my hatred of craft activities. I'll bake, I'll sing, I'll run round parks but craft is my kryptonite.
