DD has been having a df for about 3-4 weeks now. DH gives it to her at 10.30am and then she feeds around 3.30-5am. It helps in that I go to bed early and so only have to do one feed in the night but it has not helped her to sleep longer stretches, I think she probably slept longer stretches before we started. What do you think? She is almost 14lb now and a hungry bub.
