This is my go-to activity bag for travelling with my toddler boy. The Elmo cd is on permanent play in our mini-van (The big kids would prefer Katy Perry but Elmo keeps the baby quiet while I drive). Whether you are travelling by plane, train or minivan…these activities will entertain your toddler and help to save your sanity. 
- Ziplock Bag (Loblaws) – perfect catch-all to keep the activities organized.
- Fisher-Price wheelies cars (Toys R Us) – excellent for pretend play.
- Beep Beep Moto (Mastermind Toys) – vroom vroom!
- Best of Elmo cd (Indigo) – for listening entertainment.
- First Years Take and Toss (Shoppers Drug Mart) – tap spoons together like drum sticks.
- Fish Crackers (Loblaws) – perfect toddler (and big kid) snack.
- The Very Hungry Caterpillar (Indigo) fun to read and touch
I have a 3 year old son and I agree with everything you posted here. One of my MUST have’s, for my son, is a Hot Wheels car. I have to have at least 2 on me at all times. I make sure I have them in all of my purses because, God forbid I ever forgot one, he would be lost without it.
