Phone should put here!

The phone in our bedroom always MIA, and everytime if we can't find it we know where it gone. As our boy will place it in his diaper bag, this habit start when he is less than a year old before he started to walk. But the frequency has increases as every nite we have to look for the missing phone from the usual hiding place. Sometime when we ask him to put the phone back he will look for his phone in the playhouse and attached it nicely to the adaptor and again put our phone back to the bag. I and hubby still wandering what's wrong with the phone being in place with the adaptor. Why he always 看不顺眼。。。
