Baby crying all day

ufi

My 14 weeks baby boy had been sleeping well up till last night. He kept waking up crying, every other hour and would fall asleep in my arms. He wasn’t hungry but just kept waking up. He didn’t sleep well through out the day today and has been so fussy. His poo and pee count is normal. The only time he’s not crying is while feeding. This is happening for the first time. Any suggestions?
