I?m looking for some advice on expressing breast milk for the odd expressed bottle feed (probably once a week when I want a night off). LO is 4 weeks old and feeds every 3-4 hours exclusively breast fed from birth. He has surgery on day 2 and so I had to hand express and then use a pump to keep colostrum going and encourage the milk to come in (he was on a drip for 3 days and didn?t get to the breast until day 5). So I know I can express. My question is this, when (as in time of day before after or during a feed) should I try expressing again. He tends to feed off both breasts and certainly drains the first one and sometimes the second- so not sure if I would have any milk left to express after a feed. Might I just have to give it a whirl and hopefully supply will kick in to the new expressing demand? Any hints and tips grateful received. Want to give it a whirl if I can, but certainly don?t want to upset supply (or him). And would 5 weeks be an appropriate time to try him on a bottle (of ebm of course)?
