Hi, I have decided to give formula to my girl ...

Hi, I have decided to give formula to my girl for 3 feeds out of her 5 feeds for the day. The other 2 i will be giving her my breast still. Does anyone know how i wean her onto formula for these feeds? Her current feeding patern is: 7.00am - breast 11.00am - breast want to replace with formula 3.00pm - breast want to replace with fomula 7.00pm - breast want to replace with formula 10.30pm - breast Someone told me if i dont do it carefully and slowly i can get mastitis. Any advice on how to do this the same way will be great! [Edited on 06/02/2008]
