I started with her on the teeter with the slight drop we had worked before. After a few time of that with no problem I changed table to increase the drop. Apparently it didn't bother her!
I do still need to emphasize to her that she works with me no matter what else is gong on. She can get distracted by the other things going on around her, but she is just 7 mos. old. We'll continue to work at home without distractions and in other environments WITH them as well.
