Whilst I haven't had a chance to use this yet I'm sharing it anyway. Our daughter is 3 months old and when we discovered we were going to have a child I decided I needed a few "daddy" skills. After some pondering I realized learning some origami would help; there is always some paper about and if I could distract a boisterous toddler for a short while whilst out and about it would be worth it. So I set about learning a few hats, birds and boxes (and also an origami waterbomb!). When I'm at work or with friends and they see me practising, I mention I'm learning origami as a way of subduing a small child. More often than not, they tell me that they too know a few simple folds, and it does indeed work.
