I'm planning on getting a Boba. Ellie is 2.5mo and i only wear her in the ring sling and woven wrap. Lately i've started wearing her in the infantino ecosash with her legs in the froggy position. I was planning on getting the boba when shes about 5months. Me and hubby are going away with her for 4 days. We're planning on bringing the ring sling, woven and boba. Do you think she'll be old enough for the boba then or wait longer? most ppl i'm seeing start wearing in the boba between 6-9mo?
