I am so sorry for all of the breast feeding issues, I have definitely experienced them as well. I also had a big meltdown, Writermama, but mine was day 5. I get tiny little mini meltdowns occasionally as well, probably every other day. I warned DH to keep an eye on me and make sure I don't have PPD, but so far it seems like a very reasonable amount of baby blues.
I know it is not that helpful, but with the BFing issues (I had sensitive and then bloody, cracked nipples, followed by mastitis, ouch) what has helped is time and trying to be a stickler about the latch. It is hardest for me at night when I am too tired to be persistent, but it is helpful for me personally to force myself to get out of bed (which wakes me up) and go sit upright and focus on the latch. Grayson was 12 days old before we were able to have an entire day of good latches. My nipples are healing and I am finally feeling much better.
Babytoes- my little one's lower lip is often sucked in, and I found on the Kelly mom site or somewhere else during my googling a technique for using the index finger of the hand that is supporting the breast to pull down on the chin (while baby is suckling), it pulls the lower lip out and helps babe get a better mouth full of boob. This is hard to explain and also hard to get the hang of while nursing, but we are pretty good at it now.
Of course it is helpful to see a LC, which I did, but not until day 14 and our issues were basically resolved by then, funny how that happens.
Spughy- my kids look a lot alike as well, and often I have that time warp feeling, VERY weird!
Scruffy- it's so funny to see their little heads next to such a big breast!
Mayday- I'm so sorry about the prolapse and know next to nothing about what you're going through, just wanted to offer support. Hugs.
MPs- sorry things are so crazy at home, I am appreciating that DS1 is 5 years old and pretty mellow! Sending you mellow toddler vibes!
