Traveling with a baby Q’s

Hi there! Hoping someone can help answer a few baby related questions for us. Traveling to Phuket/Krabi in the coming weeks and wondering how much we’ll need to pack with us from home.

Where can you buy baby diapers in Phuket? The same question goes for things like jar (or pouch) baby food?

Are these things easily accessible?

Also is it possible to buy swim diapers in Phuket or should we plan on bringing them with us?

Thanks for any insight! Trying to pack as light as possible 😅 no easy feat with a 10 month old.
