all of the sudden my 7 1/2 month old has been fighting going down for naps. it is like she is not even tired. I tried putting her down at 2 hours of A time and no go. then tried 15 min after that did not work and now she is going close to 3. Last night she woke up several times during the night so not sure if this is related. dhe ended up napping well yesterday so I know she is not overtired. she never wakes at night. and she is not sick. she is moving more and could possibly be getting another tooth? could this all contribute?
