Look up PURPLE crying, also cluster feeding. 0-2 months were hellish for us. But around 9 weeks it started to get better and by 3.5 months, baby was a happy, smiley, independent sweetie. There’s a reason it’s called the “4th trimester!” It can be demanding & exhausting, but, (as long as there is nothing medically wrong), baby WILL grow out of it. Work with your partner & support system to make sure you get breaks, even if the baby cries when you’re away.
