my son has been crying ALL day and idk what's wrong with him... I've fed him, changed his diaper and even gave him gas drops but nothing is working. only time he isn't crying is when I'm holding him... and it's been like this for a couple of days, but today has been the worst. what's crazy to me is it's only during the day, at night he's really good.. he's only 3 weeks old. any advice? 😞
