8 month old question worried

My baby girl just turned 8 months & isn’t clapping . My niece started clapping at 6 months. I’m getting worried & frustrated. She babbles , mama , dada , nana , baba, & num num sometimes it sounds like she saying hey & she is basically crawling but also tries stand up on her own she puts her butt in the air on the bed. I’m concerns are she isn’t clapping she’ll puts her hands together but don’t clap but she tries to wave. HELPPP when did your baby clap ?
