My mum has just bought me the most beautiful cot set- bumper, sheets, fleece blanket, quilt etc etc etc all the bits that go with it all. Then DPs family said that we can't use any of that stuff because all the baby can have in it's cot is a fitted sheet and one of those blankets with holes in it. Is this true? I don't want my mum to have wasted the money and the set is so beautiful I hope we can use it.
