My DDs started with a new childminder in the Autumn as previous one stopped minding. I cried when previous CM told me as she and her husband had cared for DD1 since she was 7mo - she is 3.4yo now.
My previous CM recommended my new one to me - and had already recommended us to her!
The big bonus for me with both these CMs - the new one is great too - is that they work with another CM and have an assistant too. This means that there have been very few occasions (1 I think in nearly 3 years) when I have had to find alternate care due to CM having to close due to sickness within their own family.
Other things I like are, again in no particular order:
pets - both CMs have had animals; cats, rabbits, hamsters. I am not big on animals myself but DD1 is and loves having the chance to interact with and clean out animals. Also means that, one day when she is older, we will allow her to have a pet and hopefully she will have some idea about what it entails.
policies - I like that both CMs have let me take home a file full of stuff after the initial visit. It might be slightly different in that I was already pretty certain of signing contracts on both occasions as both CMs were word-of-mouth recommendations.
own and other children - my DDs have a lovely time playing with other children. Both CMs had/have own child/children and I think this helps my girls see CM as a mummy-figure. Own children are, in almost all cases in my experience, older and of school age.
meals - my current CM does provide home-cooked meals for lunch. She will also provide breakfast - although my girls have usually already eaten by the time I drop them off.
diaries - we love reading these and DD1 likes to read it with me and add more details about what has been included. Occasionally a photo will be put in as part of an observation and DD1 loves telling me about these and looking at herself. There are occasional days when the diaries are not completed and I miss the brief notes then!
trips out - park, library, playgroups, etc. DD1 used to love doing laundry and going shopping with previous CM.
Really I want a CM to be interested in my children and to offer a safe, comfortable environment that gives something along the lines of being a 'normal' family home. I like the fact that there are a number of children on different days so DDs develop social skills and do get something that is different from what they get when they are home with me - which they are for 13 weeks of the year when I am not teaching.
I could not put my DDs in an environment where there was smoking but am happy for them to chill with 30 minutes of Cbeebies during the day sometimes.
I also like CMs to be flexible but to expect children to follow their rules - with some regard to parental expectations. For example, we do not use time out or naughty seat or anything but are happy if CM opts to do so and explains situation to DDs.
Outside space - but garden does not have to be huge - just enough space for outdoor play like paddling pool or sand/water or wendy house type things. There are 3 parks close by for bigger running sessions.
Walking - I am happy for my DDs to go in car with CM but like the fact that they walk to/from school, library, parks, town etc regardless of the weather.
Lots of stuff to do - singing, playing, crafts etc - often stuff that we don't get to do so much of at home during term time.
School pick ups - DDs will go to local school as that is where CM drops off/collects from , even if I was to get a job in another local school (there are 4 in town but they would go to the one that works best for CM - and 3 are all very good schools anyway.
Probably other things too - I do feel that both CMs I have had have been/are fabulous and are an important part of my daughters' lives. DD1 was with CM1 from 7mo and DD2 started there too at 7mo and transferred to CM2 a month later - I rely on them to care for my girls so that I can work - which makes us all happier.
