So my son is 10 months and isn't crawling or pulling himself up yet. If he wants a toy out of reach he just stretches all the way to reach it. He really hates tummy time too. At his 9 month appointment the doctor said I should consider physical therapy if he's not crawling by 10 months. I know some babies just don't crawl and some babies develop slower. I need suggestions on what to do. Should I still wait to see if he will crawl on his own or take him to physical therapy?
