My youngest is now 12 months and will be walking soon, she's very small for her age. She wants to be held all the time so I want to find a carrier for this summer where I can still have my arms free! I have been using a Baby Bjorn which I like, but I don't think it will work as well as she gets bigger. What do you use? I don't know how if eel about a ring sling (we have one) it just doesn't feel sturdy to me.
