I wasn't sure which topic we were discussing this previously, so I thought I'd start a new one to give an update. I tried out the hands on the knees technique to get the children to lean forward this weekend, but it didn't really work out for me.
I almost forgot about it, but as I was struggling with one child to get him to lean forward, I remembered the hands on the knees technique. When I told him to do that, he just reached way out to put his hands on his knees, but continued to hold his face and body away from me.

I think I tied it one other time, but didn't seem to help much. Oh well, my other way still works most of the time.
