Hi I am 5 foot 8, not petite and bought a large one from the shop but after watching the vid realised it was too big so went onto the ps website and ordered a med which is so much better. After i fold and put it on I lower dds legs and bum in first putting her bum in line with he pocket. i keep the shoulder part quite tight so her little head doesnt get swallowed up and can poke out the top kwim... if you want pm me and ill put some pics on fb so you can see how she sits

cheers,
natty
