M.P.
We are not at the 2.5 yr old point yet! But, I am going to recommend a book that I consider SO helpful. It is "Healthy Sleep Habits, Happy Child" by Marc Weissbluth (sp?). It has taught me SO much about infant/toddler/child sleep habits and every new stage we hit, I find myself continuously going back to that book!! There are even helpful sections that talk about how to transition a child after events like a move, etc. SUCH A GREAT BOOK! Totally worth the $15...I got mine at B&N, but I have also seen it at Target in the baby section by the sleep aids (mommy bears, sleep sacks, etc.). Good luck!! :-)
