fussy baby!!!

Lyndsay

baby boy is almost 4 months old, second boy, he is very fussy lately. last few days, started maybe 3 days ago, he has episodes of extreme fussiness. He is breastfed. takes a paci. I am thinking teething, growth spurt, or gas. any other babies things with this problem? (hebwas diagnoses with colic at newborn but we had seemed to be over that about 2 weeks ago maybe)
