I just need reassurance from ebf mama’s

My baby boy is five months old and is exclusively bf I only pump when I am feeling extra full well because I’m always home with him since I don’t work.. but at one point I was pumping every time we nursed.. well right after to be exact so feed on one side and pump the other you know like they tell u to do but for the last month I just stopped bc I have a deep freezer full of milk and my regular freezer in the fridge also has tons so I just said wth I will just stop now and pump only when I am feeling extra full and typically I am pumping once in the morning and the rest of the day we latch. But I’m a bit concerned and this is just me because at our last appt doc just said he looks good no concerns at all but we only see her every two months and I’m just wondering if anyone else can help me but when I do grab a bag of milk like from freezer normally a bag holds 4-6 ounces my baby will never drink more than two ounces. Maybe on some occasions I can get him to take at least three but normally he stops right at two.. I just wonder why..? I don’t push it because he will fuss but thought I’d ask see if anyone else has experienced anything like this. Thanks in advance mama’s 💕
