Yes go for it!! If the grants are not used then the council will stop offering them anyway, and as others have said if you dont want to buy any pretty nappies then you can always lend them to a friend. Little lambs for example I think do trial packs for around £50, there are probably lots of trial packs for about that price. Or night nappies?
Thanks ladies, I've sorted out my stash and sold my 4 Ebay fluffy cheapies that were giving dd builders bum and ordered 4 bg v4's...boring but I like them! So that's me all set, upgraded my stash for free
..and to ease my conscience I will pass over a few of my bgs once I'm done to my friend who is ttc
