I get really nostalgic especially when it comes to my children. Almost to the extreme. I hate throwing away things they've made or drawn in fear that I will forget what they were like at that age. So I try to remember to take photos of things they've made or written so I can throw them away without feeling so bad. Because I can't keep every paper that they ever make.
In Max's workbook that he does before bedtime it had a page that showed them how to draw different things using shapes. The next morning Max drew these balloons and colored them.
