3 week old feeding time??

Hi!

My 3 week old babe has suddenly shortened his feed time - from 30-45 minutes per breast (😮) to 20 minutes (ish) on the first breast and 5-10 minutes on the second breast. This change occurred over a roughly 48 hour period. He is swallowing more efficiently now (every suck or every other suck) and he’s gaining weight at a good click. Seems satisfied after each feeding, so I’m not particularly worried.

Did anyone else experience shortened feeding time around this age?
