Questions To Do With Dolls..Help ?

Firstly,Is it okay to still have fun and play with dolls ? I love Liv Dolls Loads there like my favorite dolls ever. I only have two Liv's..Sophie & Alexis.It seems like im growing up fast and I don't have much interest in dolls, which is quite strange.I want to have more fun playing with my Liv dolls. I have run out of Idea's. I also have a Youtube Account which I make doll videos on but I only have like 5 videos. I also want another Liv doll for my birthday (Schools Out Daniella).My mum said that I already have Bratz and Barbie dolls. Basically a Medium Size suitcase full of dolls. I want to get another doll for my 12th birthday next month at the moment im 11. Can Everyone Answer All My Questions And Best Answer Will Get 10 Points ! Thanks x
