It's a fact that kids love snacks. No matter where they are, they'll always keep calm if they have snacks with them. So, remember this when you are about to go on a family trip- have enough and more snacks! If a train or a domestic flight that you expect to come at one particular time is late, kids will be the first to fuss about it, and at this instance, lollipops and chocolate bars can really help you keep them decent for some time.
