Hey Yvonne, i totally understand how you feel, i am in the exactly the same situation and just last night i had the sense of failure as a mummy too. I was breastfeeing him initially then cos his weight increasing very slowly so on the 5th day i started to express out my bm and bottle feed him as suggested by the PD, so that i know how much he is drinking. Now when i want to latch him, he also treat my nipple as a teat and bite on it, thus very painful, at first i endure the pain cos at least he is sucking directly but the next day he dun even want to suck liao, so no choice now i just express out my bm and bottle feed him. Some mummies from the forum shared with me their experience and say we just have to persist, but everytime when my bb try to latch and he fail to he will feel fustrated and cry and seeing him like that make me heart pain and also i feel he is like rejecting me, so i gave up. But look on the bright side at EBM we can know exactly how much bb feeding and easier to control, and it is less tiring then bfeeding then pumping out the milk after that. That is how i console myself.
Regarding the bb stop crying after ur MIL and dad carry, some mummies offered me some reasons and i found it quite true. You read the post earlier today. Dun be sad, we are first time mummies, we still got many things to learn. I think as long as we try our best can liao, we will definately still need help from others one.
May, you try pumping more often, eg, if you are pumping 4hrly, try decrease it to 3rly. And i will always use a hot towel to massage my breast first, for about 5 mins then i start the pump, i make sure each time the milk 'sprays'out. If it doesn't then i massage again and try pumping again. initially i pump every 4 to 6hrly, when i feel like it, then i realise i cant catch up with my bb's increaseing appetite, then i started to pump every 4 hrly then now 3 hrly. So far it has helped to increase my ss. Even at night also must pump. but at night i only pump once, either after his 2am feed or his 5.30am feed cos i still a bit lazy.
Otherwise you can try domperidome/stementil. You got to see a doc for that thou.
