I feel like we have a lot of toys and things to do [and I'm always reading the threads asking for suggestions on these topics] BUT not much keeps my son interested for more than a couple minutes.

Things he DOES love right now:
-cars on ramps (little people city skyway ramp)
-bubbles outside
-kinetic sand
-lego trains

Things I try and he spends less than 5-10 minutes on:
-play kitchen
-regular legos
-train table [maybe I need to change the layout or let him start trying to do it?]
-magnatiles [thinking of adding the expansion pack as I saw MrBee suggest to someone else..?]

also wondering if a toy rotation would help........

what is your 2.5 - 3 year old really into??
