milk supply with expressing

For those with slightly older babies doing full bfing with some expressing, did you find your milk tapered off as time went on? I had a prem babie and started off expressing only getting 200-300ml each 3/4 hours. now I am BFing fully apart from the last feed at nite which we bottle and I do 1 express, but I have only been getting 60mls (most 100ml). i have been expressing for 5 months now, but part to full bfing for 4 of those months. Have any of you bfing for 6+mopnths found your express supply has tapered off, bt your milk supply still ample for baby? i am worried i will eventually need to do formula topup for the nite feed (really don't want to BF for that one, is her fussiest feed and she usually takes 160+ ml and i only express of 60ml so don't think she will get enough and then wake in the nite).

Definitely -- my pumping supply almost completely disappeared, but I still seem to have plenty when DS feeds directly.

It's quite interesting -- I think that as DS has got older, he has also changed the way he feeds (in terms of sucking, IYKWIM), and after using the electric pump for months with no worries, I don't get anything anymore using that, but I can still fill a bottle hand-expressing.

Wow that's really interesting and makes me feel quite abit more comfortable. funnily after posting this last nite my electric pump motor died ARGH so i used the manual bits but a new electric motor won't arrive till tomorrow so I may have to try and be brave and do the last nite feed via BF instead of expressed milk in bottle. She is often quite grumpy ont hat feed so am worried... but i guess if i never try i will never know. will have a bottle on standby just in case perhaps!
Thx for the link missshell i will go to that now and have a squizz.
interesting katz that you get some hand expressing bu tnot via electric, what pump did you use? I got an avent and have used a medala before too at the hospital while she was in the NICU. How do you reckon your DS has changed his suck?
I must say E's BFing is a lot better now that in the early days and it is usually quite a pleasure (apart from when she bites.... not looking forward to teeth time).

hmmm maybe in time i will need to get better at hand expressing, i was no good at it when i tried at the hospital, but i was a total newb then i guess!
