High maintenance 20 mo

So my boy has never been an easy baby he is very strong willed and let's you know all about it. I can't just take him to a restaurant if it has a play area we are generally golden unless he throws a tantrum then I'm generally SOL. Am i the only one? He has never just sat in a highchair. He will at home for the duration of his meal and then he immediately wants out, again, he has ALWAYS been like this. It makes it so i cant just take him to my family's dinner even at their house because whats the point how will i eat? He doesn't just sit still. Ive tried toys games tv i am telling you everything. Does it get easier? Am i alone? Any suggestions?? Everyone i know has easy babies who just happily sit there. My kid has legit NEVER done that.
