Don'tmind, I could have written your feeding paragraph almost word for word. I'm having exactly the same problem; my baby is usually ok during the day, but at night she's feeding for 5-10 minutes, falling asleep (we've tried all the usual tricks) but then crying out to be fed 5-10 minutes later. And this can go on for hours and hours and hours. I'm breastfeeding, but have started expressing so my husband can help out during the night. We have formula as back-up too as there are some days when she feeds so much I literally don't have time to express enough (I'd love to build up a stock but I've no idea if that will ever happen!). She also hasn't regained her birth weight yet (she's a big baby).
Pinkbear, my baby is good at latching on to both sides, but she has had a lot of practice (see above!)!
I don't get pain; I've been told if you do it means the latch is wrong. I'm still on painkillers after the c-section though, so maybe that's why! I do feel a bit sore after a lot of feeding though. I do what Rue mentioned, and pinch my boob into a shape so she can fit lots of it into her mouth (deep latch).
Regarding bras, I'm loving my Bravado bras. No worrying about the correct size (other than S/M/L) as they stretch and shrink to size, and they are so comfortable.
I definitely took too much to hospital. We were told to take a few packs of maternity pads, which half filled my bag, but I didn't need any as the hospital provided them while there, and also my lochia was virtually non-existent after my c-section (I didn't need the mats I'd bought for waters breaking/ lochia at all!). I bought way too many pads after reading stories on here, I'll have to keep them for the next one!
