My 22 month old son is 31 pounds and 35 inches tall.  He's a big boy and has been in 24 month old clothing for a while.  We also use cloth diapers and have an issue with pants fitting over their bulkiness.  I bought a set on a different website and absolutely love them!  The fabric is soft yet durable and extremely comfortable.  It is my goto outfit for him when we're at home.  They are tall enough for him and have extra room.  We should be able to get another 6months to a year out of this set.  Well worth the price!
