Hi everyone, I'm new here and this is my first question. My son is 12 weeks old and I love him more than life. My problem is he cries soooo much. He's happy in the morning for about half an hour then he becomes fussy. Throughout the day he changes between smiling and laughing and crying and screaming at the top of his lungs. He'll be happy then suddenly dissolve for no apparent reason. I don't want to call the doctor for something that is normal or he'll just grow out of, how much crying is normal at this age? Shouls I be worried? Thank you for any help you can give me!
