"I'm a registered nurse. If you're visiting the hospital with a baby, toddler, or any small child, NEVER let them crawl on any floor in the hospital! It might look very clean, but it's absolutely NOT sterile, or germ-free, in any way! You don't want the bacteria, germs, or viruses that health care workers have walked through to get anywhere near your child's mouth, eyes, or nose. I'm shocked and horrified any time I see someone put their young children on the hospital floor to crawl around and 'explore' such a dangerous and contagious place."
