Do i need to buy a movie ticket for my 2 year old?
Usually if they're going to take up a seat, they have to pay.
Probably not, but I think it all depends on the actual movie theater that you're going to. Your best bet would simply be to call them and find out straight from the horse's mouth.
Unless youre going to smuggle him in jk it depends on the theatre
Same here, they usually don't charge you
Depends on the movie theatre. Just ask the people there.
Why don't you ask the theater you're going to?
