We have a 4.5mo old and have taken her on her first "family vacation." We're on day six of a 14 day trip involving about 5hrs of airplane travel (which she handled very well) but she has has awful gas pains since arriving. Every night involves at least one shrieking session lasting 30-60mins with smaller bouts throughout the day spaced by about 1.5-2.0hrs.
She has no problems at home. Food sources have not changed (including mother's diet). The only real difference between our vacation destination and home is the humidity and heat. It's very humid and cool (~80°F) at the destination and very dry and very hot (~110°-115°F) at home.
We use gripe water as needed and probiotics daily.
What's the deal?
