It's my fault: I was saying on the other thread that I'm not sure on the "services" bit, confused me. Sorry.
Since yesterday I've noticed other childminders saying "childminding services", so while I'm still not completely sure I like it, others use it, and so I'm sure people know what you mean. Don't worry! Don't change your posters.
I LOVE your webpage, and your childminding looks great. Good luck. And good luck with the webpage sideline. Good for you!
