My LO is 10 weeks, and I just started back to work in the ER last week. I only work a few shifts a week, in addition to graduate classes, but they're all over the place, e.g., 9a-6p, 10p-7a, etc. I started pumping once a day around 3 weeks, and more often when we started her in daycare at 7 weeks to get ready for me to back. When pumping I've been consistently outproducing what she drinks -- sometimes more than twice as much. (E.g., while she drinks 8 oz in daycare, I pump 20).
It never seemed to be a big problem, but the more I read, the more I think I have oversupply and sometimes overactive letdown. Esp on the side that seems to be faster, she sometimes coughs and pulls off with a little angry cry before latching back on, dribbles some out, etc. BUT she is not fussy/colicky, has a great non-painful latch, yellow poop, good weight gain. I just naturally did one side per feeding from early on, but not true block feeding.
This weekend I had a particularly frustrating day where she would unlatch at letdown and I was squirting milk a foot into the air. And then between feeds, I was leaking around my Lily Pads and through bra-shirt-baby carrier. So, I'm trying more disciplined block feeding now.
On days that I work, though, I am lucky to get two pumping breaks squeezed into a 9-hour shift, and I am worried about this decreasing my supply. I know that a lot of advice tends to be to wait for your body to settle in to a routine, but I am never going to have a routine!
I guess my question is, should I even bother trying to "fix" my oversupply? Is there any risk that block feeding plus days with irregular pumping will have a negative effect on my supply that I won't be able to remedy?
