Petallus I don't agree with coercion either, and like others think that the money would be better spent supporting mothers of all ages through better midwifery and health visitor advice.
There is a lot of coercion not to breastfeed in some families.
18 year-olds may be legally adults, but I wonder how many 18 year-olds' pregnancies are actually planned and how many 18 year-olds are mature enough to cope with the physical and emotional challenges of pregnancy, childbirth and suddenly being responsible for another human being, that women twice their age find difficult enough.
I'm for supporting them, not bribing them.
