There is time to babywear...and a time not to babywear. I've heard lots of moms say that they're done babywearing because their child has begun walking. Pshaw! I myself was in mourning when my first daughter seemed to lose interest shortly after learning to walk. BUT after the novelty of it all blew over, she had a renewed interest in being worn...and I was a happy mama!
Wearing a newborn is always wonderful...they're so sleepy and snuggly at that age. A Sleepy Wrap is a wonderful way to wear a newborn as it does a fantastic job of mimicking the womb.
When babywearing a child that has learned to walk, you're mostly back wearing at that time and a Soft Structured Carrier (or Buckle Carrier) is a fantastic option. My favorites for wearing older babies or toddlers are the ERGO, Action Baby Carrier or the Boba.
Even now that my oldest daughter is 3 1/2, she is still worn. She loves to be worn in the Scootababy and in the beco Butterfly II on my back.
So, don't let walking throw you off track. Give your babies some time to discover their new found world and then let them come back to your back for some more babywearing time!
