11 month old not pointing or waving

I’ve brought up concerns to the pediatrician but they didn’t seem worried. He doesn’t have another appointment til 12 months.

My son will be 11 months on the 7th and he smiles and laughs literally all day. He’s an absolute delight to be around.

But he’s not pointing or waving like my friends’ kids. I know babies develop at their own rate but I’m a first time mom and scared. I feel like I’m failing him.
