Watch above as Arizona Cardinals rookie cornerback Patrick Peterson deflects ESPN's Skip Bayless' discussion of Peterson's size (6 feet, 220 pounds) on Wednesday's "First Take."

Bayless thinks that Peterson, who was taken with the fifth pick in April's NFL draft, will likely move to safety as he gains some weight in the NFL.

To Peterson, it's funny people would bring up weight with him.

"I was a pretty big baby. I was about 9 to 10 pounds when I was born," said Peterson, who was born in Fort Lauderdale, Fla., and went to college at LSU before making it to the NFL. "But I guess you can say that since the age of 2, I've been pretty fit."

And Peterson, who is one of the fastest rookies in the NFL, is hoping children today get fit too.

Peterson has joined up with WAT-AAH!, a brand of bottled energy water aimed at kids, to spread the message of healthy hydration and create awareness against childhood obesity.

"I know it's going to be difficult because kids today think water is boring, but we need them to change their minds," said Peterson, who recently participated in the NFL's Play 60 initiative -- a national campaign to encourage youth health/fitness and physical activity for at least 60 minutes a day."I drank a little bit of everything as a kid but I wasn't big on soda. I didn't drink enough water myself."

Rose Cameron founded WAT-AAH! in 2008 with the goal to reverse kids' dependency on sodas, sports drinks and sugary drinks, and to persuade them to drink the only healthiest option: water. WAT-AAH! has gained acceptance in more than 1,000 schools/districts and was recently named as the exclusive water for the Beyonce Knowles and Let's Move! Flash Workout Event.

"I have a fridge full of the drinks," said Peterson, who will start Sunday against the Carolina Panthers. "If they let me bring them on the sidelines, I'll be drinking that."
