we are planning a trip to Europe in late October and it will be quite cold there. any special shopping we need to do for our 4 year old to keep safe in the weather?

in addition to what Neeta said, just make sure to carry thermometer, and your baby's essential medicines that you use for fever, cold and cough. check with the doctor. these will help in case you have to take care of basic health issues but are not sure who to get in touch with while on vacation.
