This probably won't be very popular, bu isn't the worlds population big enough without having to pay people to populate it even further? 

My Mum raised four of us with no pension, let alone a baby bonus - She did quite an old fashioned thing called 'Work'.  In those days we didn't have expensive child care....we had neighbours and relatives = extended family network, which unfortunately these days we've been regulated out of it seems.

If not, then what stops us from just minding each others kids for concessions back and forth as we did in the old days?  Even if that involves a few bucks 'donation' between friends for the trouble? 

I remember us kids having our hair cut by one of mums friends in return for taking her kids on weekends while she worked.  What went around, came back around.

I never supported the baby bonus - can you tell?  Plenty of kids living in poverty already who need it more.
