I have a 10 wk old DD2 and I need to start expressing as I am having problems with her bed time feed, she is really unsettled ( I suspect overtired) and she does not feed properly from the breast, but seems to be happy with a bottle. I have tried expressing, but so far have only managed a few ounces and I am also confused about when I am supposed to do it: before, after or during feeds? I did not breastfeed my DD1 even if I really wanted to ( long story) so this is all new to me!
