For the past year or so, the twins have been OBSESSED with puzzles. It's really Reid who pushes the puzzles. He is always the one that gets them out, but Cort likes the companionship, so he always ends up helping Reid work them. We have a good assortment of puzzles, of the 30 piece variety, but it seems they have gotten too easy for the twins. So one day I broke out a 100 piece Melissa and Doug pirate puzzle that I bought for Pierce at a yard sale last fall. It's for ages 6+, and Pierce complains it is too hard and won't work it.
