Dash is at least 22 lbs now (1st birthday next week!) and I've got him in the hip carry position in my wrap. Earlier this month, we were traveling with the two kids and our flight was cancelled. While we waited over two hours for the airline to release our luggage (and gate-checked double-stroller!!), I carried my beefy little guy in the Maya wrap the whole time as he wanted to be bounced, rocked, or slept in it while we waited. We traveled from 9AM that day and didn't get home until 4AM the next morning. He was in the carrier for over five hours total that day. The only resultant issues on my part were heat rash all over my torso, due to an inadequate A/C system on the plane/airport and carrying a sleeping heat generator on my side (he's like his father -- as soon as he drops off, he starts to heat up and sweat). My back was just fine!! And the Maya wrap fabric is strong but very light -- it contributed very little to the heat issue. A great option that I discovered on my trip: using the wrap as a tether!! If you run the rings on the Maya wrap down the fabric so they snugly wrap around your child's torso, you can hold the end of the wrap and let your child toddle around without running off. Fabulous!
