I am now on trip with my baby to Canada. My baby is 12 months old. It is free of problem because weather and food is so nice here.
For your question of milk feeding. Are you still breast-feed to your baby? If not, try to give her fresh cow milk instand of formular when you reach UK. Baby over 12 months could take cold milk, and doesn't need bottle boiling. My baby try many new food here and she enjoy quite alots!
