Thats it really dd is 2.4 and has recently taken to lying on her tummy, putting her blanket between her legs and dry humping it!
It happens mostly when she is tired, but can be at any time of day. I find it a bit disturbing TBH, and have taken to telling her it is only to be done in her bed. So now she asks to go to bed at reglar intervals
How "normal" is this and what should I do, if anything, about it?
