I've worked in a variety of nurseries and am a NVQ childcare assessor now, so see my fair share of others and without a doubt when Ellie was born it was a childminder all the way.
I completely disagree with the comment about children been behind in speech and understanding development. If anything I've found Ellie has come on more than I'd suspect her to at a nursery. She gets the social interaction from the other children that attend, and goes to groups at the children centre everyday she attends. Towards the end of the day, Ellie also gets 1-2hrs of one-to-one time as she's the only child left. This is perfect for her, especially for her age as she really does need it.
I know at a nursery, as Ellie is 'easy' going and never makes a fuss, she'd be left to her own devises and prob wouldn't get the attention that she gets with her childminder now.
Also I love the first hand experiences that Ellie gets day to day! The childminder once asked me if she minded taking Ellie to the dentist with her (she only had Ellie that time) and if I did, she'd rearrange. I told her thats the exact reason I choose a childminder. At nurseries they have to 'simulate' going to the nursery, or only learn about it through books, etc - While with my childminder she gets the first hand experience. Fair enough she'll come with me when I'm older, but I wanted her to be in as much as a homely environment as possible where she did everyday things like we would do if I was at home.
Ellie's also the same as another poster, she doesn't take well to other people. She doesn't cry or become upset, just quiet and amongst a group of 12-24 children this wouldn't suit her. It took her a good 2 months to finally come out of her shell with the childminder and intend on it been like this until she goes to school, I wouldn't want her to keep changing room and staff.
Another thing Ellie isn't your average child for her age. She would never suit a baby room and would much prefer a toddler room, so wouldn't see it fair on her been stuck in a room until her designated age to be moved up to the older room. Where as at the childminders she plays with what she wants and has activities planned purely on her interests and abilities, not the 'group abilties and interests'
You need to remember that all childminders need to be qualified (or training) to Level 3 in childcare and follow all of the regulations and curriculum's. They must plan and observe children exactly the same way as nursery's do so far as the learning and development, nothing should change - it all depends whether you want your child in a large group with a number of staff or a smaller group with 1 staff member who's always the same.
My childminder got outstanding in her ofsted report last month. If one person can do this alone whilst looking after the children, then you have to question why some nursery's with 10+ staff can only manage to get satisfactory?
