My little boy isn't doing either yet ... Hell clap with me as in he has his hands on my hand but he's not doing it on his own properly yet so I wouldn't worry
My LB can clap but only claps when I don’t ask him lol any time I ask him to clap his hands and I clap my hands, he just looks at me 😂 then 5 mins later, he claps on his own accord! No waving for us yet, but I’m constantly trying lol
My little one only waves at her uncle 100% of the time ( he taught her to wave) every one else is hit and miss.
