ke sure the pocket is around your waiste and not your hips. Make sure straps are as wide as possible, so don't bunch them.Place sraps through pocket. Ppull straps tight at collar bone level, and at same time pull excess strap from under pocket. Make sure the straps arecrossed over at around breast height. Tie straps tightly.

If u get frustrated put it down have a cuppa and practice later. Don't try and practice when u have a screaming bub, you'll never get it when panicking. good luck
