No sleep

My baby is not sleeping. Like hardly at all. I feel like he’s deprived. He wakes up every 2-3 hours at night, and he takes like 20 minutes naps during the day about 2-3 times a day. Can you imagine how exhausted I am?? Idk what it is. I feel like it might have something to do with his eating habits, he eats solids usually 3 times a day but at least twice, but he still only drinks 3 oz about every 3 hours. He’ll be 7 months on the 24th
