9 month old not waving or clapping

Anyone else? She started crawling so young (6 months) and we felt so ahead of the curve but she’s been taking a break I guess on the milestones. She used to mumble ‘mama’ ‘hi’and ‘dada’ but only mama now and just other random sounds without meaning. She cruises furniture like a champ and all the physical stuff but I try to play peek a boo and she just watches and giggle in my baby book it says they should play along? She does respond to her name but it seems like most babies are clapping/waving and she is not. Are we expecting too much too soon? FTM here
