So tired of having baby on my boob 😩

Let me start by saying this is my 3rd baby and the first I have been able to EBF and I am SO grateful and so proud of myself. I honestly have PTSD from my last 2 breastfeeding experiences and this has been so much better. All that to say.. it feels like he is ALWAYS eating. He's gaining weight great and peeing and pooping up a storm so I know he's getting what he needs. Half the time I feel like it's a comfort thing (he doesn't love pacis), and the other half feels like cluster feeding. Especially at night. It feels like every night he's on my boob from like 6pm until we go to bed. Luckily he's sleeping well otherwise I would lose my mind but I just need SPACE. I feel bad because my other kids wants to cuddle up and read books or be near baby and I am just touched out. Anyone else? How do you deal?
