clapping, waving hi/bye, "so big"?

My daughter just turned 7 months. She isn't waving, clapping or doing "so big" yet. My 2 year old was just diagnosed with autism so I think I'm being hyper vigalent with her but it's a concern for me. She is almost crawling, smiles at faces, laughs,  rolling everywhere, sitting unassisted and can now get herself into the seated position alone, she says baba, responds to her name and can stand with support for 15 seconds but isn't pulling up. Should I be concerned?
