Starting to crawl

My son will be 7 months on the 14th and he’s been squirming his way around the floor this week. Since yesterday he’s been real fussy every time I try to put him down on the floor. Is it possible that his legs are feeling sore from being so active? His wake windows have shortened from 2.5 hours to 1.5-2 hours and he sleeps anywhere from 30 minutes to an hour. I just wanna know if anyone else has been experiencing this too.
