Very fussy baby, please help!!!

Doricia

My baby boy is about to turn 3 mo next week. The past two days he has been very fussy and eating every 1 to 2 hours. He has been eating longer and off of both my breast. He is very fussy. Cries all day and even cries while feeding. I've never had this issue with him before. I'm not sure if its gas, colic, teething, or growth spurt. Please help!!!
