We are going to Italy in about 10 days time. DS is on amoxycillin, and will need to be the whole time we are away. We will need to take two bottles of 100ml through airport security. One open bottle - and one to start later in the week. They will need to be kept cool. the bottles are small enough to comply with liquid security restrictions (100 ml), but what about ice blocks? Can I take ice blocks through security to keep the meds cool?
