It used to be me or Bee, with "help" from our son. But he's building a LEGO plane all by himself tonight! He comes to me for help when he can't find a particular piece in the big LEGO jumble currently on our living room floor. Or when the pieces don't fit together, which is usually a sign that he missed one of the earlier steps.
Who builds the LEGO? When did your LO start building LEGO sets on their own?
