Where's Monkey?

A couple weeks ago Weston made a new "imaginary monkey friend". He is always asking where monkey is and spends a lot of time "looking for him." We never find him, but he is always somewhere like out in the snow, or in a certain store, closet, car, under his crib, or elsewhere. I thought it a little strange for him to have an imaginary friend so young but I looked it up and it's pretty normal. It's developmentally a way for him to practice his communication.  He is always saying everything about monkey. "Where's monkey?, Is he in there/here?, he's working, he's at the store, he's finding bananas, monkey went bye-bye, give monkey this, let's find him!  His language has exploded the past few weeks!  He is awfully concerned about monkeys well-being and his whereabouts. He asked me with his cute concerned look if monkey was okay several times today.  It's so funny. I love this little boy. I've read this is very common for a "first child" too.  It will be nice for him to have a little brother to talk to soon:)
