Sounds like something they should give out at the hospital on birthing day. A footballer's daddy-cup. "Here, wear this till you're kid is 15". Sounds like a truly fun endeavour, though I have no wee ones, so only the slipped bike-seat is my nuttular nemesi.
Oh I have done that, the slipping bike seat, nightmare!
A cup given out at birth might be a very good idea :0)
