I need my energy back.

At 11 weeks and a could days I am still so tired all the time. It hasn't been easy to keep up with a 2 year old and try to take care of the house. Not to mention my 2 year old is s very mischievous little ball of energy. I've always said that it was like I was on parenting autopilot with my 8 year old. She was just so easy. Even today she is very responsible and helps with her sister. Luckily I have a wonderful understanding partner and he does help pick up some of the slack. Hopefully I will get some energy back soon.
