Elsie has made a pretty miraculous recovery (I think so anyway). Her nose hardly ran today and you could tell she just felt better. She still struggled with naps but that may be a separate issue.
Abigail woke up with a hoarse sound in her voice and I ended up wiping her nose a few times during the morning but she has been okay for the most part. Let's hope it stays that way!
For your pure entertainment, here is a video of Abigail and Elsie playing in my kitchen. The loud squeeler is Elsie, who is laughing hysterically at her sister!
