"The reason, it is illegal to regularly look after children without being registered is because it is not safe!
Does your Friend have Insurance, first Aid, child protection, do you have a contract, so that you know that she will definitely have your child when she says she will, not change her mind at 7.30 in the morning when you have to be at work for 8, all these things do and have happened with unregistered Childcare."
A childminder has no guarantee of being safe either, they may have insurance but it doesnt stop accidents happening. Its simply there to financially protect the minder not the child.
Friends may not have insurance, first aid, child protection etc but then neither do 99.9% of mothers!
As for hours changing, I see posts on here re childminders wanting to change hours, not willing to be flexible, cutting days down or giving notice all the time so not a really valid argument.
I would much rather use a friend than a minder. I would know the friend and have built up a trust with them. Minders are usually childminders for the fact that they wish to earn money whilst staying home with their own children. I would imagine a very high percentage have their own children so its not necessarily their first choice of work.
Friends and families will always have other peoples children, its lovely to be able help out each other. Quite daft to say it cant be for more than 2 hours at a time.
