Extremely Confused and Lost

My 2 1/2 year old is a very very picky eater, she doesn't talk much either. I always hear that by her age she should be saying short sentences or putting words together. She's not there yet. She says words but not hitting her milestone on that one. Shes very active, loves running, climbing, and she's an extreme dare devil. I constantly am in motion with her. I'm trying to help her develop her vocab skills but she doesn't seem interested at all, we've sort of developed our own language and way of communicating. Sometimes she's not too aware of her surroundings and she's always bumping or falling. In the evening I have to sleep next to her and she cuddles me ALL night. I don't know where to go from here or how to help her. But I love her soooo much, I do my best.
