10 week old ....

My 10 week old son still wakes faithfully every 2.5/3 hours at night to eat. He isn’t the best sleeper at night because of this but during the day he eats way less and only naps for 15 mins at a time making him CRANKY. This has been happening for a couple weeks now. He’s so exhausted! I’m not sure why he eats way more during the night on a schedule but barley during the day and he only naps a few mins at a time. I can’t really complain too much because he used to be extremely colicy and would take hours to get him to bed at night. Now (knock on wood) he fussed and may cry a bit but is still in bed by 10ish then up every 2.5/3 hours. I’m exhausted and regretting going back to work already 😭 😴
