PPL will boost IQ

Oh really. The push to extend Paid Parental Leave just got sillier. UnitedFuture say that as research shows breastfeeding increases IQ, mothers should be paid to stay home and do just that. I wonder if they are going to demand that breastfeeding become a requirement for receiving existing PPL? Or that receiving the DPB makes breastfeeding mandatory? And for how long?

Well, as you brought it up UF, what about the heretical idea that those most able (financially and emotionally) to raise children might be the ones with higher IQs and a mother's IQ is an important factor in determining the child's? It's not an implausible idea. Of course nobody dare say so. Except that mad professor who thought we should put contraceptives in the water supply so people who wanted to become parents would need to take a positive action instead of just drifting into it with no thought as to who would pick up the tab, resulting in a bias towards the uneducated.

The best family policies should be the same as the best policies for individuals - low flat tax, choice in education and tax rebates for health insurance.
