I have beeen invited to 2 baby showers in October, both mums to be are friends with one another and will be attending each other's party. One friend is asking for a pack of nappies and the other are asking for gift vouchers. How much should the gift voucher be? Also one pack of nappies sound too cheap, should I just give them both a voucher for the same store on the same value?? How much would be reasonable?? And which store? Mothercare??
