Not clapping or waving?

So my little guy just turned 9 months on the 25th and he hasn’t shown any interest in clapping or waving AT ALL. He’s been saying momma, dada, and just a total chatterbox for months now, can stand unassisted for a few seconds, pull himself up on stuff, walk with his walker, and is responsive to our facial expressions and words but no matter how hard I try he doesn’t want to wave or clap. Is that normal? Should I be worried? Lol the FTM anxiety is strong today!
