Perfectly normal! Not all babies crawl/cruise. Even my 8 mth old baby is the same as yours. He cruise instead of crawling and loves to stand while holding onto me, my hand, arm, my back or even my tummy then he thought he's 8 yrs old already he'll try to let go of his hand 😂
I have another 4 older kids. From what I remember, no. 2 and 4 skipped crawling and to learnt to walk at 10 and 11 mths old. No issue so far with their balancing whatsoever. They're 14 and 10 yrs old currently.
