Ds is 6 mo and due to a variety of issues seems to be preferring to take expressed milk from a bottle in the day time. He still feeds directly at night time very happily and still wakes several times, having a full feed each time. I definitely want to be able to continue direct night feeds. I have up to now found expressing fairly easy, getting around 120-150 mls in 5 mins or so but if we continue down this path of expressing only in the daytime (I still always offer a direct feed first btw) then am I risking a dwindling supply or at 6 months will it be established enough to continue this long term?
