Delayed 11 month old?

My baby is almost 11 months. Not crawling, walking, waving, blowing kisses or saying much. She says Dada and babbles at least once a day. In the crawling position she will rock back and forth on her knees but won’t actually crawl. Will kinda army crawl for things close. Will not pull up on furniture or take steps. She will put weight on her legs if we help. Has anyone been in this same boat with a delayed baby? Did they eventually catch on? I have a ped appointment next week.
