I think this has been discussed here before. It sounds good in theory, but how does a woman prove she is breastfeeding? Health Visitors don't visit anymore in many areas, as I learnt on AB, so won't see it. For some women it is not easy to do, and is unfair on them.
I have just seen this on TV and the Mums who have tried the scheme said its not the money (tokens) its the support and group stuff with other Mums that they found helpful....so why not spend the money on support and not on tokens?
Sp,curiously for something that is so natural it can be very problematic for many reasons - my main down on the voucher scheme is that Mum's who already struggle are given another label as a failure.
I was very lucky with my two and fed them for over six months, but not without some Mastitis which is agonising at times.
It's ok once you get the hang off it, but you have to remember to swop which side you feed from or it can cause problems - by the time I got to feeding thing 1 and thing 2 I could feed them both at the same time and read a book (not something I would have done in public though).
Personally, I don't think mothers should be rewarded for breastfeeding their babies. They either want to or they don't. It should be a natural thing, not something to be paid to do.
