A box for each kid K-12 ... I had a professional organizer at my house (what a treat!) and she suggested this system for pictures and papers, etc. 1st year, 1-2, 2-3, 3-4, pre-K, K, 1st grade - 12th. So simple, but so brillant.
Fill a glove with beans, pearled barley, rice, etc...give a few pats and slip quietly away. Rated 5. This was a LIFESAVER when my daughter was an infant. She went through a phase where she needed my hand on her back to go to sleep. I also needed to do...oh, everything! This was the solution I came up with on my own and it worked like a charm. I would nuke mine in the microwave to make it warm and helped soothe her too. I HIGHLY RECCOMEND this for anyone with an infant in the same situation.
