How long will he sit there?

We stopped by ToysRus the other day and they had a ton of stuff on sale/clearance. I've been wanting to get Jake a little table and chairs for his room. He loves to look at books, color, play with play-doe so I thought he would love a little table. They had a lot on clearance so we looked through them all for about 30 minutes to find just the right one. Finally found an adorable Cars themed table. (His room has a bunch of cars stuff so it was perfect). He thinks it is the greatest thing he's ever gotten I think. He sits at it non-stop. He also has a cars television so we have a constant play of disney movies playing through it while he does everything at his table.
