Maybe play some board games or watch movies. Make pizza's or taco's with some adult supervision. You could do facials and nail paintings with mom's help. Or maybe do some arts and crafts. The list is endless on what you can do. The main thing is to have fun (:
I think you should do crafts or like find out what they like then go on from there I'm 13 and I'm more into talking about life but I get motivated if there's food. Maybe baking, having a dance party, karaoke? If you have a machine. Makeovers, dress up, I don't know really because I'm more of a tomboy and at sleepovers I usually go outside and wrestle boys 😂
Order a pizza bring some movies over, play truth or dare. Stuff like that.
