Tips for travelling with 15mo to all inclusive

em

We booked (a much needed) all inclusive vacation to Punta Cana.

My son has a combination of whole milk and formula. Can I trust the whole milk at the resort? Should I only do formula? Where do I boil water? Is the bottled water the provide okay to use?

If you have done this before, how did you wash all the bottles, bibs etc.

Any other tips for travelling with a 15 month old?
