FWIW, Yes, you do need to clean all bedding as part of the first treatment. But the stuffed animals, not so much unless the kid sleeps with it (them) a lot. Although this wasn't necessary, we used this as a forced excuse to do a deep clean of the house, which we really should have done anyway. We did clean the sheets and towels vigorously, though, and with segregation. In summary, segregate all the linens and stuffed animals that are in use, place them outside in plastic garbage bags so they don't get wet or damaged, then put them in your washing machine and wash them in series before you put them back in use. Then, do it again in a week. Oh yeah, and in between, give your kid a RID shampoo. It's a hassle, but if you take advantage of the outside of your home as a storage area for possibly infected material it helps a lot. The lice sure aren't going to get inside.
