Baby crying non stop

Holy crap... my head is spinning. My newborn never ever cries unless she needs something. But tonight at 5pm I fed her 4oz and she ate it all and burped great! Well 7pm comes around and she's still acting crying and she's fussing, so I fixed a 2oz bottle and she ate that, and burped. She's still fussing so I tried gripe water. That didn't help.. so I bounced with her swaddled and hummed to her and she finally went to sleep! Could this be a start to colic.. because my son started colic at the same time ( 3 weeks old). Oh yea and he's only 13 months old... somebody I need advice
