Did they discontinue making the really large legos? I can't seem to find anywhere to order a new set? My 5yo with SN still plays with this kind as he has very poor fine motor skills and used to put things in his mouth for a really long time. I have a nephew who is turning one, and I would like to order a set for him as I think that is the intended age, but I can't seem to find it. It comes in a large clear bucket and has 70 blocks that are much larger than even the duplo sets. I checked Amazon and the Lego site. Thanks in advance for any leads!
