Like others, I'm not worried. I don't know too many who would take 18 months for the same pay as 12. As it is, there are already a few families I've had who had to go back to work earlier than the year for financial reasons. If it does happen and parents choose this option, I'm okay with it too as I prefer kids over 18 months. My ratio is also 2 under 2 but finding older kids isn't that bad here....but definitely infant is the higher demand
