Going on an airplane trip for the first time with toddler?

yes diaper bag counts as carry on so put ur purse in it or vise versa and yes u can bring juice and snack and yes they charger u for stroller and they will take it with bag claims and she will be fine she will love it but when plane moves hold her tight and go weeeee and make sure to give gum cuz going up will pop her ears and they will scare her but the gum helps to not feel it after that she will sleep its like a car ride she will love it i tho the same but my kid liked it except the ear thing
