Guess the vagaries of nature. My boobs tend to take turns on which one is more productive. But the left side is always sore and seems to have a much harder time......... maybe something to do with how my daughter drinks.
Turns out she has a lip tie (this is the upper lip is tied to the gums by the piece of skin - like a tongue tie but is the top of the mouth). She will be having surgery on this in a few weeks - will find out when on Saturday (it will cause jaw and tooth problems if not corrected - could cause severe buck teeth, among others). Am hoping that having this corrected will make BF more comfortable for me.
I think my sister had what you describe as lip tie. I just did a google search of "tight upper frenulum" and found many other people who experienced the same thing.
My sister did have hers taken care of. She was around 5 years old, and it was anything but surgery. She was given a little bit of gas and the dentist (regular family dentist- not a specialist or even children's dentist) used a painless laser. No bleeding, no stiches, no pain, no recovery, no tears. My stepfather watched, my mom looked away :)
I also suspect it's just natural variation. I imagine they have different amounts of glands and such. My boobs vary.
With my first DD, righty always made an ounce more than lefty. Then I had mastitis, and after that bout, lefty always made more than righty. This time around, for the first 3 months, righty always made an ounce more than lefty. Recently, they have been closer to even. I don't know the reason for the change.
they don't have lazar treatment available here in Philippines, so it is minor surgery.
It will be done by a pediatric dental surgeon (it was picked up early because my adopted mother here is an orthodontist). They will give her a mild sedative and then a local anaesthetic. They have to remove the skin and a bit of connective tissue. Think it will take about 5 minutes. Don't think any stitches. Will find out on Saturday.
The easiest and simplest answer is usually a subconscious preference on our part. You tend to nurse on the side you favor, whether the reason is that arm is stronger or because you want your dominant hand free.
I had a strange issues with absolute non-production of milk in the right side, but thankfully I trained my breast on the left to produce enough for both. Talk about lopsided!
