Sleep Tight, my baby!

We have always been blessed with a good sleeper. Sarah takes her full naps, whether they are the 2 hour naps 2 times a day or the one 3 hour nap she's taking now.  She never gets fussy when she's tired and she goes to bed without being rocked or carried.  We plop her onto bed and then Sarah manages to fall asleep on her own by licking the crib sheet or blanket (equivalent to a pacifier or thumb, both of which she didn't pick up, thank goodness!).   She sleeps at 8:30pm at night and wakes up at 6:30am in the morning.  When we wake her up in the morning, Sarah rarely cries. She just wakes up, opens her eyes and then she is off to doing whatever we have plan for her.  I am seriously not exaggerating. Sarah never had any issues with sleeping, well, maybe until now...

For the past month or so, Sarah refuses to go to bed at night.  As in any toddler, she wants to play and don't want to stay confined inside her crib.  Even after the whole bedtime routine, she still doesn't want to sleep. She would cry a good 10 minutes before eventually going down for the night.  Sometimes we have to sternly tell her, "Sarah, go to sleep, go to sleep!" By that time, it's close to 10pm, not the time we want to go to sleep.  Just when we think we can finally rest, Sarah wakes up in the middle of the night screaming her lungs out. We've used the Cry It Out method - but sometimes she would cry so hard that she gets congested and eventually throw up.  Then it becomes a big dramatic affair to calm her, change the crib sheets, and change her clothes.  Not something I want to do at 2 am in the morning!  Sometimes she would fall back asleep but not without first having one of us get up to pat her back to sleep. We can't quite understand why she's not sleeping through the night. Perhaps she's growing her back molars that giving her pain? Perhaps she's cold at night? Don't know???  All I know is that I hope this is only a phase and I will get back my good little sleeper back!!
