I am trying to come up with some gift ideas for my son's 2nd b-day. He has a bunch of Megabloks and likes them but doesn't play with them very often. I was thinking of trying some Duplos since there are so many fun sets but not sure if they would get ignored too.

So should I wait for him to show more interest in the Megabloks or try the Duplos as something new? Anyone's kids prefer one or the other, or any other suggestions? He has a starter set of Magnatiles already but isn't that into those quite yet either. Thx!!
