I collected about 0.1ml the first day. Several days later I managed to get 1ml. Just remember a full feed for a newborn is only about 5ml to supplement so any amount is good.
I tried for a few days and got nothing but tried this evening and managed to get about 4ml from one side only. I've heard that if you keep trying it gets easier/you can get more but echoing folks above that sometimes it doesn't come in until after birth. Stay strong and don't put too much pressure on yourself
Only a few drops are expected and many of us don’t get any before baby arrives. So any you are collecting is a huge success - bravo!
