Britton adopted a baby son, Yoby, from Ethiopia in 2011, and insists she loves her role as a mother, but the 45 year old feels awful about leaving her little boy while filming episodes for the musical drama.
She tells People.com, ""I have the most incredible kid and we're having a great time. (But) I didn't really fully comprehend the level of guilt involved (with motherhood).
""I like to pride myself on not being a person who really functions at a level of guilt, and yet, man, I never knew I could feel so guilty when I work 16 hours and I really don't get to spend enough time with my son. It's awful.""
Despite her difficulties, Britton would love to expand her family: ""I would love more kids. Sure, why not? Bring it on.""
