Sleep regression is back

Since the last time I posted, I've been really tied up with Emilia. She has been very difficult to put down for sleep. Good naps are very rare now and just to make her go to sleep takes a long 30-40 minutes sometimes. She hasn't acted like this since 6 months. It could be due to her teething. I don't see any other teeth breaking out just yet but she's been gnawing at things a lot and of course there is lots of drooling. She becomes a monster when it's her nap time and bedtime. She screams like she has never done before.... it is so loud that I can feel my eardrums vibrate. Also she definitely prefers our bed in the master bedroom over her crib. When she throws crying fits, I sometimes move her to the middle of our Queen size bed with a pillow on each side of her head. She quickly becomes peaceful and falls asleep within minutes. I don't know what the deal is. Does she want a larger bed already? Does she like the scent of mommy on the bedding? I know it's not about co-sleeping because I don't have to lie down next to her to make her sleep. She doesn't even need me there; she just likes our bed. Hopefully this sleep regression too will pass like the last one at 4 months.
