for the longest time, milo seemed only interested in destruction. i don’t mean that he ran around destroying the house or anything (well, of course he does do that from time to time), but if you pulled out the blocks what he wanted to do was knock down what you built. suddenly that changed and now he want to build! or at least to stack the blocks. and he counts while he does it, which for the mom of a child with a speech delay, is pretty exciting!! go milo go!
