Colic??

Brandy
I think my daughter is coliky she turned 3 weeks old yesterday and the past 3 days we noticed she was getting more fussy and has had gas so I thought maybe it was an upset tummy but now she is crying more but as soon as she is picked up and put on our chest she stops crying. I've gave her gripe water.
She sleeps great at night and doesn't cry it's just during the day! Anyone else think this is what it is? Do any of you moms have some advice to help? Please and thank you!!!
