Visiting MMP with small kids, what do you recommend?

Padres fan coming in peace.

Wanna get some tix to take my wife, father in law (huge Altuve fan) and small kids (18mos and 4 yrs) to their first ball game at MMP. Would love a section that isn't too crowded and has easy access to get up and do stuff nearby if the kids get bored. It's my first time there, what do you folks recommend?

BEAT LA!!!! (we have that in common eh?)
