My son asked for a season ticket for the first time this year (he is 7), again I was slightly worried 90mins may be too much on a cold wet Tuesday night or Saturday afternoon when his mates wanted to play.
Season Ticket in the east stand is holding up great though!!!
Advice I'd give would be
1. Get into the family funzone at 2.00-2.15ish and embrace the cheesy-ness, get programme signed & photo's with players (as well as a shot on the x-box)
2. Take lots of treats...if enthusiasm begins to wane rock out a pocket full of sweets!!
3. Make him feel like one of the guys, (not condoning under age drinking) but whilst I stand having a beer I get him a lemonade in a pint glass (That's his beer.......Your meant to be his cool uncle!!!!....make him feel like a footy fan not just a kid)
4. Buy him a golden gamble or ask him to pick a player he thinks will score and have a couple of 50p bets to keep him locked on the game - I end up paying out whatever the result tho

5. Get a burger/or hotdog (Aren't great I know but's he's 8 ...its a treat day for him)
Ultimately yes I lot hinges on the footy but I've learned over the past few months...what he goes home and tells his Mum is usually 20% about the footy but 80% of his day...what he has done, eaten, laughed at etc
