I wouldn’t be concerned. Just practice pointing at things a little more. Maybe even take there hand and do the gesture for them and point at something. They will definitely get the hang of it. Don’t worry at all.
My kiddo won’t wave or clap ever but will point to things in a book and my facial features (eyes, nose, mouth). Today she did peekaboo for the first time with her hands. I think some kids just prefer different gestures. I’d rather pass away before high fiving someone, personally😂 I was worried about clapping for months, she’s literally fine though lol. I wouldn’t stress unless your pediatrician is worried.
My lil one don’t point either but do everything else
