Just curious for what you guys say, my daughter is just over a month old, and there are some times when she just seems to cry & cry😔 She'll be fed, have a clean diaper, not too hot or cold, burped, I'll check to see if anything is tight or uncomfortable, etc., and I'll keep offering food when she's crying like that, she's not sick, but nothing seems to work. But I'm wondering if it's because she's starting to fight sleep a bit?
