Really? In "most cases"? My wife and I, and all our friends who have kids (which is the majority of our friendship circle now) used the baby bonus(es) to buy, you know, stuff for our babies. Like clothes, sleeping gear, safety stuff for round the house, prams (one for the first and a dual P&T when the second came along ... both off gumtree). We used it to pay for the ridiculously high electricity bill caused by having a heater running all the time to keep the temperature optimal so our baby would sleep properly in our shitty rental house in winter. We used it to pay for proper car seats, to have those seats properly installed, to install a metal grate so crap doesn't fly from the back of the car into our children's faces when we stop suddenly.

Whilst there were some pretty high profile cases of misuse (especially when it was given as a lump sum payment when it was first introduced as pork barrelling measure to gain ground amongst "Howard's Battlers") I think your claim that it was misused in "most cases" only goes to show that you don't have kids.
