Fixed! I hope . . . .
The dryer vent guy just left and it is already smelling better in there. I really hope that was the problem. I had no freakin’ clue about cleaning dryer vents. My childhood home had the dryer right next to an outside wall. It probably had 2 inches of hose. My dryer vent goes up an all the way across my house. The guy said we ha 0% airflow and a few loads away from a house fire. Scary!
Moral: Go get your vents cleaned right now!
Elsa started randomly puking in middle of the night, so that was fun. She only puked two times (midnight and 1 am), but I was awake all night just waiting for more. The first time I caught her before she really started puking (sad that I recognize the subtle sound of a pre-puke stomach gurgle) and was able to hang her over the side of the bed. I’m sure my carpet thanks me. Not so lucky the second time. I have a ton of laundry to do today. Bah. At least I can do it without killing us all.
