We have a box of Duplo at home but usually no one wants to play with it. (such a waste!) Instead, Denver and Gladys play Duplo at my bil's place during the day. Maybe it's because of the companionship they enjoy since there are more children around and also because they already had fun in the day, hence they are not interested to play their own set back home.
Gladys was feeling bored and so I suggested to play Duplo.. she is only keen if Mommy joins in and plays with her. So there we are sitting down, stacking the Duplo pieces to make houses and trees. I wonder when will be the next time they'll open the Duplo set to play again. :p
