Aficionados know, babywearing is NOT just for babies.
There are so many reasons to continue using baby carriers once a child can walk and many carriers that can comfortably accommodate a toddler or preschooler. Some people don't realize though that wearing toddlers is an option until their kids actually reach that age. Then, they continue babywearing or shall we say toddlerwearing out of convenience and even necessity. If you're already wearing your baby often, it's easy to see that just because they have learned to walk does not mean that they no longer need to be carried.
In fact it's quite the opposite. Babywearing helps with so many issues that make having a toddler challenging. If you think about it, toddlers are more challenging than infants because they're totally unpredictable. You never know when you'll need to carry your toddler!
