My baby the only one not doing anything?!

My LO really just started rolling over ( she has done it a couple times at 4m- but never intrigued her)  she sits up really well by herself but that's about it! I see SO many babes crawling/ rocking / inchworming/ pulling to stand at before or at their 6 months. 
 It's hard not to compare but I guess it's nice to know if other babies are like mine!
