You can help them crawl, but you can't make them
Avery had all the signs of being ready to crawl, but she just didn't want to. She would much rather pull herself up and cruise or walk then crawl anyday. I couldn't stop obsessing about it.
I did all the tricks. Tummy time, toys just out of reach, even holding her on all fours to see if she'd support her weight. Nothing changed. Then one day she just got up and crawled like she'd been doing it for months. Baby's are funny like that.
