Anyway, I have a newly-3 year old kid and tickets to an NFL game here in
Philadelphia in November. So, I'm wondering, can we bring him?

Are you planning on putting th 3 yr old in his own seat?
IMHO, football games are not really the place to bring "lap" children.
However, if you can afford a ticket for a 3 yr old, all the more power to you!!

We took both DD and DS to baseball games (minor league) at about 3yrs, and took
them to hockey games at about 3 1/2yrs.
word of warning:
The kids had a blast, but it wasn't like I got to pay attention to ANY of the
game. It was just a 3 hour foodfest.
