11 month old development

My baby will be a year old September 1st. He makes a lot of noises and babbles- he even has said dadadada, but he won’t say mama, or dada, or associate those to us. He also can’t clap or point. He waves his arm(s) a lot, too. I’ve read that it could be a sign of autism. I’m a little concerned because his development seems a little delayed. We practice and work with him a lot. Is this normal?
