My 2.5 dd has never been a good sleeper. It is like a roller coaster. She will sleep well for a few weeks/months and then get thrown off by a late bedtime, holiday, illness, etc. We are then starting
all over.
Please read "Healthy Sleep Habits, Happy Child"(weisbluth by Marc Weisbluth (I think he wrote it). This book saved us and taught me how to get her to sleep. Earlier bedtimes help and sometimes crying it out are the only things that can get her back on track. Before going through this, I swore I would never let any of my babies cry it out, but I was so sleep deprived and desperate I was willing to try anything. It works for her. When the pattern of not sleeping begins, I will always check to make sure she is ok (just not wanting to sleep) and sometimes I do go in and check on her.
