I happened across this page which describes parental leave in different countries by accident. (No Mom-we are not pregnant!)
The only 2 countries on there that do NOT have paid maternity leave are the US and Australia.
To be fair, there is no information on a tiny country in South Africa called Lesotho and the former Russian controlled country Latvia. So, maybe, there are 4 countries that have no paid maternity leave.
Draw your own conclusions but I really enjoyed the mostly unpaid 5 1/2 months I had with my little guy. Babies are so helpless at that point it felt really strange to be taking him to daycare when he could hardly hold himself up or crawl (and that was at 6 months!) They need their mommies at that point.
