My little one is growing so fast I'm going to have to take some size 1 pampers back. I have about 4 of the big packs... which were bought for us. The problem is, when they were bought, the shop, Mothercare said that they would not take them back if they were wrong. My question is, where WILL take nappies back, with no reciept...? I'm hoping Tesco will let me...has anyone ever had to do this?
