Lately Lucy has been very interested in putting things into other things. She has a nice wooden egg and cup toy and a nice plastic ball and ring and funnel toy, and both of those will hold her intrigue for many minutes at a time, but she (of course) likes to venture into non-toy items as well.
So we might walk around the house and find a bath toy in the bathroom garbage can, a hair clip in a glass of water; diaper spray on the record shelf, or, in a feat that still puzzles me, the knob of the hepa filter inside a sock. Usually we find these things when we aren't looking for them and cannot find them when we are, so very often these days diaper changes involve a wipe wet with water instead of spray and we have a pair of pliers handy for turning on and off the white noise when the knob goes missing.
We've taken to storing the bathroom garbage can up on the counter, because even worse than what she might try to put in is what she might try to take out. Curious monkey!
