My son has been napping literally all day, but he's still so tired. He was in the middle of rolling over and he just started wailing out of nowhere for no reason. I picked him up and held him close so he calmed down and the second I pulled him away from my body to adjust he started wailing again. It's the most heartbreaking sound. He must be growing again 😖
