You make Gak, of course!
This was a great project for both kids. Emma helped put the ingredients together (white glue and liquid starch), and both stirred them together and mixed in some food coloring. Emma had fun showing George tricks. George (who seems to be completely over his tactile issues) rolled, stretched, and squished his blue goo.
It is such a relief to have my two kids finally finding a middle ground they both enjoy. All weekend they have played together, Emma has read stories to George, they both played with this goo for an hour, and then back to dress up and jumping in his room. For so long, Emma has been upset at having a sibling she couldn't play with. For so long, George has been unaware of a similarly sized creature sharing his home. Now, they have a relationship. Not always a peaceful one, but that's normal. And normal isn't something we see much around here, so we'll take it!
