Hi just a quick one, I normally express around 9:30 and get 3/4 ozs in 15/20 mins, this morn I expressed around 8:30 (baby was hungry and like to do it at the same time) and only got 2 ozs in 15 mins, is that just a coincidence I got less or is it because I was doing it an hour earlier and my body wouldn't expect it until 9:30? Thanks
