I have just signed contracts for an after school child, 3 hours every day. I explained all contract with her and she was happy and signed and has left deposit. Now I have had an e-mail from her saying that she does not agree with having a 4 week notice period and that she wants it reduced to 2 as this is what she did with all other childminders. Can someone please tell me how to diplomatically tell her that no Im not happy to do that and that I couldnt give a flying one what other childminders did for her?! 
Actually not bothered if she doesnt agree to this and pulls out because I hate people who think they can dictate my terms of business to me, i think its really disrespectful.
