I use a childminder for my son.. she's amazing!
When I was looking for someone I found it hard to find someone I liked.
When you meet them try and meet them when she's working.. I met one childminder and ruled her out because she was more preoccupied with me than with the children; even meeting with me I'd expect the priority to be the children. One little girl asked for the toilet while we were talking and she was made to wait.
Ask about her views on consequences/discipline.. it's a very important thing that you should agree on. If your child misbehaves is her way of handling that how you'd want it to be handled.
Find out what her policy is for your holidays and hers. Some charge for 50 weeks of the year, some do term time, some charge you half fees for holidays. Some charge if they're on holiday. Mine doesn't charge when she goes away but I pay half if I go away. I only have a term time contract as I work in a school so she doesn't cover any school holidays for me unless I book extra slots which I never have.
Also what contact do you have when they're there? Mine sends pictures all day and I love being able to see what he's upto and that he's happy.
Mine only provides snacks. I can pay additional for breakfast, it's something ridiculous like 50p a day which is nothing. I provide lunch, nappies, wipes etc. She doesn't do an evening meal but not something that bothered me.
She provides trips in her price, zoo, national forest parks, sea life centre, etc. She takes them out every morning somewhere. even if it's just a walk to the local park. She hasn't done days out due to covid but she did before. In the afternoon she does activities at home, messy play, painting, crafts. She rarely just leaves them to just play, it's always structured in some way which I like.
Ultimately I'd say go with your guy instinct, I ruled loads out simply because I just didn't warm to them. If I had the slightest niggle or doubt I'd keep looking.
