Baby Milestones

Simply for curiosity because I know every baby is different. My LO has hit pretty much all his milestones for being 3 months old on the 9th except the batting at toys. In fact he could care less about toys and I’ve tried multiple different kinds, hanging them, setting them next to him, and even putting them in his hand and he doesn’t reach for them, doesn’t shake them, nothing. Again I know every baby is different. He’s not batting at toys but I swear he is days away from rolling from back to tummy which is crazy to me! Anyway just wanted to see if other LO’s haven’t reached that milestone yet.
