Sorry to hear about your predicament! Those three-year-olds can be fast! I was with my two-year-old nephew this weekend and boy, I had to watch my yarn or he would run around the room with it!
Are the stitches twisted from when you put them back on the needle? If I did it, I would just leave them on the needle twisted and then when you purl, purl on the back side of the loop, once you get done with the row or round, your stitches will be untwisted and you can knit as you normally would!
Hope this helps!
