We are going on vacation to the Caribbean next week where it is going to be 85 degrees and sunny every day! Yippy! It'll be very different than the Northeast, so I was wondering if I need to be worried about baby getting too hot or dehydrated. LO will be 16 weeks and is EBF. Any tips for that and in general? Also can I take her into the pool at this age? What are the most important things to bring with us?
