My 16 week old appears to be teething. He woke up today congested, which I hope is related to the teething. Yesterday and today he only wants to eat about 5 minutes at a time pretty frequently. When he's on one side, he squirms and rubs his face, and doesn't appear to be getting a lot. I keep hearing his tummy growl, but he keeps having the appropriate amount of wet and dirty diapers. He eats well when I pump and give him a bottle, but I'm not responding to pumping very well right now. If he continues eating for such short amounts of time for a few days, will it hurt my supply?
