2 day old

Li

He only drinks about 3 oz a day, i wind him and everything and he just doesn’t want to drink sometimes, he feeds every 2hours to 3. He was born at 38 weeks and 3 days. I have a baby appointment for him on saturday so hoping that they can let me know he is actually adding weight. He poos everyday now and even sometimes poos straight after feeding.. He wees a lot too. I was told he might not drink a lot in the first week because he’s still new but he has drunk a lot more than before. Has anyone had this issue? i’m a ftm and i feel upset because i don’t think i’m doing what i am supposed to do
