Crawling help

My LO just turned 7 months and seems far from crawling. She is fine on her tummy during tummy time, rolls both ways, etc but when it comes to crawling she just doesn’t seem close. She wants to stand always. Her brother (3.5yo) never crawled but did a butt scoot to get around and was walking at 12 months. My first was in daycare at 13 wks, any advice now that I am keeping her home vs daycare? Paranoid FT working mama who relied on daycare apparently way to much
