@Tasha thank you!! Yes planning to do that too
We took a flask for boiled water for the hot shot method. Make sure you find bottled water that is low sodium and always boil like you would tap water. We packed lots of ready made bottles too x
When we were out there we just boiled bottled water and we had some of the ready made formulas too, we just added formula to cooled boiled water later in the day which we have always done, my sister used a rapid cool though but just added the formula last xx
