My husband is always on my case about how our daughter isn't crawling yet?

My daughter is 10 months old. She scoots backwards and can go around in circles on her belly but doesn't quite understand that she can go forward yet. My husband, every time he has her which is rare, asks her why she isnt crawling or walking. I understand after reading on sites and talking with doctors that it is perfectly ok for her not to be crawling yet. Her development is doing great although she doesn't crawl or walk. It really gets me down when my husband rarely spends ANY time with her and when he does he is upset that she isn't mobile and it gets me down as a mother cause I start to think I am maybe doing something wrong. She also cries a lot with him which I think because he gets frustrated with her and she knows it. Help please!
