Fitted sheets for cot and moses basket, a fitted sheet for the pram will depend on which pram you have bought. I have a mamas and papas pilko pramette(would highly recommend this pram) so I used a cosy toes type for that. You will also need a bumper for a cot. For night time I would recommend buying a sleeping bag, they go by other names such as dream-pod or grow-bag. They put your mind at rest when your baby is little. During the day when you are watching the baby I would just use a cellular blanket.
Also moses baskets are a waste of money, they only last the average baby 12 weeks, then
