Some may wonder what is a toddler harness... it is sort of like a leash you put on your curious little adventurer who just discovered the freedom that comes with walking on their own. There are different types of toddler harness available in the market. There are some you put on your child's wrists like a bracelet attached to a parent's wrist and there are some which goes around your kid's upper chest hugging your toddler sort of like a backpack (some styles even have backpack so you can re-use them when the kids outgrow the harness) .
