It's natural; children this age develop so quickly that they're always looking for a new challenge. But that doesn't necessarily mean more toys are in order. Try these easy ways to refresh the ones he has:
Set up a toy exchange. Tell a friend you'd like to swap some of her child's toys for some of your kid's booty (nothing valuable or prized, of course). After all, other people's stuff is always more interesting than your own.
Rotate your inventory. Put a few toys away for a month. When you bring them out again, they'll seem like new. That's because toddlers discover fresh ways to play with familiar things as their motor skills grow -- the child who once dragged a train across the floor will later be able to push it around a track he's constructed. (And if he's "driving" his old cars in the tub, don't rush out to buy a set of plastic boats -- let him be imaginative.)
Tuck away a birthday or holiday present or two before your child sees them. Break out the reserves on a rainy day, a plane trip, or a fussy afternoon.
