Tips needed! travelling with my 1 year old

Hi! I’m planning for a short holiday trip to Thailand with my 1 year old. What are the must bring items / things to take note for a holiday trip with your little? Please share your experiences~ My concerns are… do you use the hotel kettle for baby food and drink, and also to sterilise the bottles ? (I heard it’s usually dirty?) For places that do not have a baby changing room, how do you change your baby diaper? I’m planning to do it on the stroller but… what if my baby poop? 😅 any tips on this? Thanks!!!
