can children under 6 years old attend the queen latifah and common concert? If so, do they have to have a ticket if i have seating on the lawn?

Yes the child would still need a ticket, 2 and under don't

Not true. I had to purchase a ticket full price adult ticket for my under 2 year old. A woman in the ticket line with me had to purchase a full price adult ticket for her 3 month old

Yes, children under 6 are allowed, but they do need a ticket
