Hair is amazingly strong – try taking a strand of your hair and snapping it in half. Unless you have very brittle or fragile hair, you’ll likely find this a difficult thing to do.
When babies are young, they have a surprising high exposure to loose hair. It’s not unusual for a new mom to lose significant amounts of hair during the post-partum period and the longer the hair, the higher the risk of getting wrapped around a baby’s delicate toe. And, perhaps surprisingly, sometimes the hair that wraps around is from the baby itself, not a parent or someone else.
