I went shopping today and bought my pram so i was feeling very organised until I read the accompanying manual type bits and they started banging on about cosytoes and said I should buy one. I have no idea what they are and if I actually need one or not :s I'm due in July so if it's a warmth thing I'm thinking I might be fine. My early organised feelings have now faded and I'm back to feeling under-prepared and petrified :( Can ANYONE tell me what these mystical things are for?
