HELP me please!!

My darling little DD is 9mths and for the past month or two nappy changing time is becoming a nightmare. She wriggles and writhes and wants to turn onto her tummy, she arches her back and stretches out her legs so putting on the nappy is a real struggle.

I'm trying to think of new techniques to make this easier. I have given her a new toy to hold or an object she isn't familiar with (like a baby coathanger etc) to keep her attention, but have now run out of anything new and this is only a short term approach.

I don't think a hanging mobile will help either, she will be interested the first couple of times but then I will be back to square one.

I really want to nail this on the head as I am worried it will just get worse, is it just an 'age thing' where it will calm down in a month or whatever

It is also starting to happen when I dress her, she makes it hard to put her pants on.

Any suggestions would be greatly appreciated.
