Hi Ali thanks for the visit and info. i have a medela electric. i don't have morning engorgement cos i have a big night feeder (someting i hope to switch when he's older). so my breasts fill mid evening, when i'm trying to sleep. I have a HaB, a ring sling and an ergo. i also have a long piece of stretchy fabric i bought and use as a wrap, although we mostly use the hab because we didn't get the infant insert for the ergo, and we couldn't work out comfortable ways to wear the ring sling. it's still all frontal carry though, which pulls backs out of whack no matter how they're worn cos the human frame and posture was not designed for large frontal weight. i bought the fabric for high back carries but we failed at that, too.
