Where did my good sleeper go?

Sammy-Mae

Nap time?  Not a problem.  Goes down easily like she used to.  We are on hour number 3 of bedtime.  I have thought about dropping the nap but she sleeps worse without it still.  She is just over being sick.  She now won't let DH go soothe her if she is crying.  Has to be me.  She is having tantrums. She just bonked her head off her headboard on purpose.  I don't know what to do.
