I guess it depends on how long your delivery will be. I'm not sure if your hospital has Fridges
No as long as you have your name on the bag they are in they will put them straight into the fridge/freezer
You don't need to take any with you, if you are going to be in for a while and it's deemed baby needs it then someone can bring it in!
