Nursing for less than 10 min at a time?!

Kristina

My 8 week old has gone from nursing 15-20 min on in side to 6-9 min and most of the time that’s only on one side now. I will offer again and he will spit it out or even gag. How can he possibly be getting all he needs n 6-9min? Anyone else experience this? Could it be temporary due to leap?
