How many of your babies are standing?

My first wasn't crawling until 13 months. This one started crawling at 10months and standing 2 weeks later, I thought by one, he would be standing on his own because he seemed to be on track. he just started trying to get up from his 4s just last week and still no successful stand. Is he slowing down? Do I need to give him more exercises? Usually I let him do his thing. Any tips?
