Thanks for the suggestions, I have joined netmums and put a message there. Will try gumtree too.
I am moving to a new area (Walthamstow in East London) and don't really know anyone there so can't get recommendations.
If anyone here is in Walthamstow I'd be glad to hear from you!
I found my current minder through CIS (in Lambeth) and am very happy with her, but in Waltham Forest they will only send you the vacancy list (on NCMA website it says ask for full list but they wouldn't give it to me). I haven't found many suitable ones on the list.
I looked on Ofsted but there are 232 childminders in walthamstow so would take forever to go through them all - also I don't think Ofsted reports necessarily give the best indication of how good a minder is as I think my current CM's was satisfactory grade and I think she's much better than that.Ofsted seems to place a lot of emphasis on paperwork.
I have found someone who will do for now and I will see how it goes, am hoping it will be easier to find other potential CMs once we are living there if it doesn't work out with this lady.
Changing CMs is such a big step and yet when you're moving house it's just one of a hundred other things to co-ordinate with...
