I’m tired of stressing about this

Me and my son woke up at 6am this morning and I changed his diaper. It’s 12:30pm and he’s barely peed in the one from this morning. I’m putting him to my breast as often as I can sometimes he refuses. He also cut 2 teeth so idk if that has anything to do with it. I pumped after feeding on both sides and got 2oz total so I tried giving it to him in a bottle and still refuses a bottle. He’s 6 months old I feel like I’m not hydrating him enough I wanted to go to a year of breastfeeding and he absolutely will not take a bottle I tried 6 different kinds. Also he’s pooping every 2-4 days
