My DD will be 2 months shy of 3 when we leave in 2 weeks. We plan on having no carry-ons except our cameras/camcorder and the necessities for her. However as a typical mom what I NEED and what I always have with us are two different things. What do we truly need for two flight segments. A change of clothes of course - a toy or two - anything else?? She's potty training but I will probably put her in a pull-up just in case for the flight. Anything I'm missing??
