I purchased a new sterilizer in Feb 2006 for the baby I am expecting in 4 weeks. I checked it when I first bought it and thought the instruction manual was there, when I opened it today I realised that it was a mum to be booklet and their was no istuctions. I have read the back of the box and understad how to use it but there is a dial on the top of it with the numbers 3, 6, 9 and 12 on. I was wondering if any one knew what this was for. I have contcted the manufactures and they will send a manual but it may take up to 14 days. I am now a little worried incase the baby comes early. Please help
