You can try to mix these baby food with cereal:
Apple sauce
Bananas
Peaches
Pears
Carrots
Sweet Potatoes & Corn
Mixed Vegetables
Every baby has different reaction to these baby food. It really depends whether your girl like it or not. Every baby is different.
I have a suggestion, I think before you go for your vacation, you should give her a try first (now), at least you'll find out if she likes it or not before heading to your trip, right?
