This would happen to me as a teacher too. We were required to have musical instruments available at all times during free play and I bet you can imagine the beautiful "music" 3 and 4 year olds can make with symbols, maracas, drums, castanets and tambourines. I'd be trying to work on IEPs, collecting assessments, observing or screening students when a group would decide to form a band. I'd be focused on the task at hand and the noise would slowly creep into my subconscious and start stressing me out. My first instinct would be to collect the instruments and help them find quieter activities. But, that wouldn't fit into the "available at all times" rule and also, what fun would that have been? Instead, I adopted a,"If you can't beat 'em, join 'em mentality in those moments. When the kids migrated over to the instruments, I'd trade my clipboard for an instrument of my own and the instant I became a part of the noise making it stopped stressing me out and became so much fun! I quite possibly have the best memories from those moments.
Fast forward to today, I am working on my to do's and Ayden is happily playing while jabbering constantly at the TOP of his lungs. Once I realized how I was feeling about it, I stopped what I was doing, got down and joined him. We sang, made animal noises, I started hearing his jabbering as the amazingly cute thing that it really is. Joining him, becoming present in his world, removed any built up tension from the "noise" just as well as silence would have and it was MUCH more fun for the both of us.
I suppose for mothers of boys, the "if you can't beat 'em, join 'em" mentality is just as important for survival as it is for a preschool teacher! I am seeing some remarkable parallels these days as he is getting older.
