Crawling and standing

Is it normal for infant to skip crawling and went straight to standing up? My girl is 7 month 12 days old and she stood up on her own today while holding the side of her play pen. She can move on her tummy; not forward but backwards and she’ll at times move about using her backside. Is it true that baby who skipped crawling and cruising will have development issues like balancing etc? Should I be concern that she’s not crawling and/or cruising and went straight to standing?
