Babies almost never undo a ruck from up top – it’s always the bum that goes loose. The best rucks have a LOOSE bottom rail initially, then the over/under part of the process secures them. Because there is simply so much fabric pulled down under the crossover, the ruck stays put. The worst rucks (read, bum pop) occur when I fuss with that bottom rail – it’s basically a pocket, and needs room to be:-)

With the shoulders – I don’t fold, I twist each inwards a couple of times, and tie a chest belt at the base of the throat, keeping tension on the rails. Then over/under legs, bounce, and tie off. This version of the ruck has all the advantages of speed, along with comfort if bub falls asleep.

Rucks have stood the test of time for me, and I still turn to them daily. We use them as our primary back carry for their ease and speed!
