I would invest in a little blow up chair apparently it was the best thing my first brought with her
I live in Dubai and it’s going to be hot! I suggest a pram fan and avoid being outside during the day. There’s loads of lovely indoor play areas.
My friend once said she packs a tiny paddling pool and that way baby can splash around at the side of the pool or on the sand of the beach and that means you can supervise them properly without having to spend all day in the sea or pool. A good idea I thought! Also just pack a change of clothes for you both for the plane just incase baby has any accidents. Even if it's something simple like leggings for you!
