Thanks for all the great advice, ladies!
One of the l/c I saw had me try a feeding tube attached to a syringe with about 1 oz of milk. The problem with that method was that I needed a 2nd person to stick the tube in the corner of his mouth once he was latched on, and with my husband being gone so much, that just didn't work for us.
The other l/c had me try nipple shields, to try and trick him into thinking he was sucking on a bottle. This worked great a few times, then we were back to square one.
My lo has a great latch and always starts off sucking vigorously, but then starts to fuss and cry after just a moment or two. I keep trying to put him back on, but he just gets more upset, and then I cave in and give up.
I've tried pumping for a few minutes before feeding him, to make sure things are flowing, but even that hasn't worked.
I feel like a complete failure at breastfeeding, but I am glad that I've been able to provide him with ebm. Pumping takes up a big part of my day, but at least I'll be in the groove when I go back to work in January!
(trying to look on the bright side here).
Thanks again for all the tips. I will try them.
