I'm a childminder (this is my day off!!!) and I can say that one of the downsides is that I have my own children and if one of them is ill with something contagious, I can't look after other children. Over the last 12 months, I have had to shut for six days in total, because of two stomach bugs and DS had the flu just before Christmas. On the up side, I am flexible, open earlier than nurseries, don't charge if parents are 15 minutes late, am flexible with food, drinks, etc. Childminders have to take a childminding course, we have first aid and food hygene training, and many will have extra training on anything from behaviour management to language development. Many childminders are educated to degree level. It is dissapointing that some people don't see us as professional.... I do not close down because I have a bad day....
And yes I sometimes take my minded children out for a small shop, they pick new fruit and veg, we try new recipes, I tell them about how much things cost, let them pay, we count the money together. I also take them out to the cafe as I think it's part of every day life, a normal thing to do, that their parents would do with them occasionally. I also take them on other outings, such as small soft play areas, visit fire stations, do forest walks...
And I speak two other languages and all the parents I work with love the fact that I also teach their children songs and words in English, French and Spanish.
