I think Kimberley was nearly 3 when i got rid of hers and i tried everything you could think of.
The easter bunny for eggs that didn't work.
I said it was broken and we left it at the shops that didn't work.
Just took it away the screams where so bad i lasted 2 hours then gave it back.
In the end i put a small hole in the top so it went flat, a few days later i cut a slit into it and she still liked it and then finally after about a week or so i cut the whole top off and she said oh it's broken so we both threw it away. At bedtime that night she asked for her dummy and i said remember it was broken so we put it in the bin and she was okay with that.

Alex never had a dummy but Eleanor does and this time i am going to get rid of it sooner rather than later.
