J., I have a 17 month old son and he seems bored with his toys as well. We got him one of those Step 2 plastic slides. It's small enough to put inside and then you can move it outside. My son LOVES it. It's pretty much the only thing he plays on/with consistently and he is a climber. He will play with a few toys here and there but not for very long. I think at this age, they like to challenge themselves physically! So anything that he can climb on (that is safe and age appropriate), or open and close or stack are probably the best toys. Also, introduce music if you haven't already. You might be surprised at how much he might enjoy listening to and dancing around to fun songs. And if you find some other miracle toy, do tell!! Good luck!
