We're embarking on an 8 hr road trip with my 4.5 yo and 2 yo boys in a few weeks. I'm looking for some recommendations on how to make the time a little less painless. The 4 yo is super easy as he is happy coloring or watching movies. My 2 yo is the wild card as he is not into tv and only wants to watch youtube videos. Unfortunately, my data plan will not allow that. What are some specific apps that he might enjoy? People also talked about getting little toys at the Dollar Store. What types of toys did you get? Any other tips other than taking breaks when needed and snacks, snacks, snacks?
