Ok, my opinion (not as a child minder, but looking as someone who might be trying to find one):
Background is nice. Butterflies are distracting. I would say you need to choose between keeping them, with a plain background, or losing them. They give an amateur look to the site, which it needn't be.
I don't know whether your punctuation issues are because it isn't your strength, or if you were just in a hurry, but you need someone to go through with a fine tooth comb and sort it out. It is sloppy, and would put me off. There are just too many errors to do it on this thread. You need someone to go through it with you so you can change it bit at a time.
Your sample menu page has some serious underlining issues, and spacing issues. You need to change your spacing. Your underlining is the wrong weight given your font size, and the colour is all wrong. They need to tie in with each other. I would stick to the three main colours of your background, so that it is easy on the eye, and gives a 'corporate' feel. You are asking people for their money. You also have discrepancies in your font size, and some of your underlining is black, some purple, and others blue.
You need to make it clear that your 2nd child reduction is only in the event that the first child is full-time, as it can read that the first child can be part-time, but the second child must be full time. So someone could think that they can put their older child in for 1 hour per week, and then have their younger child full-time at the lower rate. It just needs to be clear & concise.
It's a bit pedantic, but I would switch the order of after school snack and breakfast to reflect when they occur in the day.
Your parental reference needs to be spaced so that it reads as a letter, with proper paragraphs. At the moment it looks like either a list of unrelated statements or a poem.
I think you either need to give your ofsted unique number, so that a prospective client could read your ofsted report, or put a link to it on your ofsted page. Neither would identify your address.
I hope you don't think I am mindlessly picking, but this is your business, and nice comments don't get you clients
