My nerves can't take it anymore ??? The son is crying like a bad word when I put him to sleep. It was daytime for the first time, just putting him down to feed he starts crying, then with a struggle I managed to put him down, today the same picture, only all day, and during the day I barely managed to put him down, on night sleep he started crying again, he cries, his eyes are red, he's freaking out His gums aren't swollen, teeth aren't poking out ? Has anyone had this?
