Nesting?

Could I possibly be nesting this early into the pregnancy?  I've been going crazy getting everything organized and I've made a lot of fun changes to the playroom.  My husband and I built this awesome ball pit.

L loved trying all the different tubes.  We plan to make the tubes more elaborate as he gets older but this is perfect for him now (13 months).  I also switched the sensory bin to homemade moonsand and bought a drawer set to house his blocks, hot wheels, and animal figurines.  Those three items are toys that get played with often so I decided to have them a permanent house in the playroom.  Everything on the shelves gets cycled through monthly (sometimes longer if I'm feeling lazy lol).  Anyway, L loved the homemade moonsand so much that I wasn't able to get his clothes off of him prior to him climbing in.  :P

  I've also been making busy boxes, an idea I took from the Play At Home Mom blog.  These busy boxes will come in extremely handy when I have to nurse the new baby, but I wanted to go ahead and make them now in anticipation of morning sickness.  If my morning sickness is half as bad as it was the first time around then L is going to need to be occupied for quite some time while mommy hugs the porcelain throne.  :(  Our first busy box is dyed rice and a few little condiment cups for scooping and pouring.  As you can see he liked it quite a bit but it's been put out of sight for now so that when the need arises it will be new and cool again.
