REallytired, it depends upon what you want for your child. I personally used nurseries because I was concerned that if the childminder was ill, that my childcare would break down. That was very important to me at the time.
However, it meant my sons were in an institutionalised setting from a young age. It was light and brightly coloured and there were lots of activities, but it was still not a home from home environment.
Additionally, the nursery staff had a high turnover and were quite young, most were in the late teens and very early 20s. They were forever changing their staff and the young girls would chat as much as they would play with the children. As soon as my sons had got used to a member of staff, then they would leave.
At least with a childminder the child would have the same person looking after them.
The difficulty in my area is that the before and after school groups don't feed a proper home cooked 2 course meal and do not offer a calm quiet area for reading or homework. For a 4, 5 or 6 year old, being picked up at 6ish is a long day. The mum then has to go home and give them dinner and then do their reading with them. A childminder would feed them a proper dinner and could do the 10 mins daily reading that a child in infants requires. This would take a lot of pressure off working parents.
An after school club picks up straight after school. A child can not do the after school activities such as Judo or Football etc. A childminder can pick up at 4 or 4.30 so that the child can do those clubs.
Childminders do not plonk their mindees infront of the TV. That is a very old stereotype. For under 5s they have to offer a wide range of toys and activities that help meet the Early Years Foundation Stage. For over 5s but under 8s a childminder may offer a range of activities, from TV to board games to Wii etc. But what exactly do you think the after school clubs offer the 5-8 year olds?! At least the childminder has fewer children so the child gets a longer turn!
There are pros and cons to both.
