Won’t sit still!!

Everyday when I’m playing with my little one it’s like he can’t sit still. I know he’s learning and exploring but I’m worried he’s not learning many skills. At first I thought he was overwhelmed with the amount of toys so I only get one or two out at a time now but he just seems so uninterested. He would much rather crawl around and try and stand with everything he can. I’m worried that he’s so focused on moving around that he’s not picking up anything else. He doesn’t like to play with me and would much rather do his own thing while I sit in the room with him. I’ve been trying to teach him to put a ball in a basket as I’ve read this should be something he should be picking up at around this age. He picks up the ball, bites it then throws it to the floor before moving onto something else. Should I be worried? Should I be trying harder to get him to do it or just let him do his own thing?
