Yeah, how are you going to sterilze the bottles? Last time we went to Macau, my husband almost took our electric boiler along (he actually wanted to get the sterilizer), so for the entire night he was washing the electric boiler in the hotel, the bottles and boiling water so he can soak the bottles in boiling water to sterilize. What a busy night for him, I don't think he has to be so scared because the spoon and bowls are not sterilize, but he said there are more nutrient in milk so germs grow fast (well, he's in the food business so I guess he knows better)
