THIS....so worth the cost.We used disposable bottles on our trip. They are calle steribottles. They sell them r babies r us and Amazon. A box of 20 is around $20. They are one time use bottles - use then throw away. My son had no problem adjusting to them either. You could always get a box to try before your trip. They were a life saver - nothing to wash or bring home!
I am going to WDW in May with my DD who will be 5 months old at the time. She is bottle fed (formula). What do you do for sterilizing bottles while in WDW? Thanks
