Need some advice from travel savy mommies out there. I am planning a trip to the UK with my son who will be 21 months old when we make the trip. I will be there for 10 nights over christmas staying in hotels thus will not have access to many home comforts. How do you clean the bottles when you travel, should i bring my own sterilizer. It is rather big... do i still need to sterilize bottles when my son is already over 1 yr? will be greatful for any advice. By the way how much do you pack when you travel? Many thanks in advance.
