Hi there,
My baby is 6 wks old and I try to express milk for those purposes as well. I've read every bit of info I can get my hands on for help on breast feading and expressing milk. I've been drinking jungle juice to produce more breast milk, Í'm on Eglynol as well and I've decided to buy Prolak tablets as well. What I've read on expressing is that it's best to do directly after a feed, even if you don't get much out. Express every day in the morning and store it untill you have enough for a bottle. Even if you express every couple of hours this will stimulate your breasts to produce more milk and therefore able to express more a next time. I've had a big wake-up call regarding the expressing situation. I thought that I would be able to express a bottle and store it, but alas maybe 50ml if I'm lucky. Your baby will not have a problem taking a bottle if it's only once a week or twice a week. I've bought Tommy Tippee bottles and my baby takes these bottles and my breast with no problems or fuss.

Good luck and take care.

Good luck and I hope everything goes well
