Genital Touching

hello My name is Leanne My princess daughter's name is Tia she is a wonder happy content very smart funny ect ect ect little 2.5 year old. ok that said the subject of my letter is for over a year now Tia has put her self to sleep by rocking on her belly with her hands {usually with a bottle in her hands} between her legs. I have read many articals that this is normal exploring and I have almost no problem with it. BUT the last few months it has become quite an issue I mean it is all the time she will drop to the floor anywhere and I mean I have lift her from the floor while she is still in the position. Please know that I do understand not to make a big deal and to make as little as possiable out of it but it is getting to be to much I can hardly get her outta bed in the morning to get her to daycare. I am trying not to make this a issue. if anyone knows any advise. she is only two I know it isnt sexual it just feels good to her. She is a very happy loved baby. Thank you. Leanne
