Random fussiness

Katie • TTC since June 2013•Endometriosis and Infertility•

So I just traveled a 2 hour time difference from lousiana to California and ill be here for 2 weeks. Prior to this my baby was eating beechnut oatmeal cereal and homemade baby food. Since day 1 of our trip he has been eating Gerber oatmeal(non organic) and jar babyfood. We are on day 2 of the trip. He has never ever ever been a fussy baby, always content and only cries when hungry or tired. Since day 1 he has cried non stop unless he's held. Gas drops dont do any relief so I'm not sure what else to try. Maybe the baby food? Could it be teething? The time change? Im not sure where to start to rule things out to determine the issue but any help or advice is welcome
