LO1 is 2.5 years old. He's the type of kid who is very active, rarely sits still and runs everywhere. He generally listens pretty well for a 2.5 year old, imo, but he does have his naughty moments as well.
For reference I also have LO2 who is 16 months old.

Basically I've avoided any event that required LO1 to sit down and behave since LO2 was born. My husband works retail shifts so I'm alone with both kids quite often and it's hard to manage them both at any sort of event.

Well now that they're a little older and I'm coming out of the fog of having 2 kids under 2, I'm trying to take them to more events and it's not going well. LO1 does not want to sit anywhere and the few times I've tried so far it's ended in a meltdown. For example, last week I took just LO1 to a Monster Truck show and the second we got there he had a complete meltdown because he didn't want to sit there, he wanted to go drive the trucks (he's never gotten to "Drive" anything so I'm not sure where that even came from). This kid loves anything with trucks/equipment so I thought this was right up his alley.

So my question is, does anyone have any tips or suggestions on how to help him? Or is this just normal behavior for a 2.5 year old and I should wait it out? I really want to be able to take him to things, especially things I know he loves, but I'm having a hard time getting him to just sit anywhere and just watch.

Thanks for any suggestions/advice!
