For a Birthday Gift from my parents Jack and I are flying to Florida for 5days to stay with My Grandmother and see a bunch of my relatives down there. I only got one seat and he's going to ride in my lap because its only an hour trip and he loves sitting with me usually anyways. Also, I will be done EPing then But will be in the process of transitioning from Breastmilk to Whole Milk so I will have ot also bring a cooler with 5 days worth of milk withme. The website makes it seem liek u shoudl bring what u need short term on the flight...but there is no way i'm checking my milk in risk of losing it!! I know a lot of you have flown recently so I wanted to get tips from all of you as far as what I can bring on the plane for him. Im flying southwest so I can check 2 bags or 1 bag and 2 things for Jack like his carseat and packnplay. Thanks in Advance for the help.
