Ok so I have 4 month old I have been exclusively breastfeeding. Well I mean I’ll pump and freeze when I’m at work but I mean I only give him breast milk no formula.

So I used to pump and be able to make 4oz, 5oz, 6oz, and some 2oz baggies to freeze. Now it’s 2oz and 3oz baggies I can pump. Sometimes just 1oz but he is still breastfeeding well. Does anyone know why I could be pumping less milk?

**ps: he had his 4months check up and his weight is good. Very healthy baby.
