💤😴💤😴Exhaustion - help please! 💤😴💤😴

Be
I am almost 7 weeks and so exhausted!!! I'm sure you all can relate. I have two other kids, a new puppy who likes to get up at 5am at the latest, and a full time job. I want to cry most days thinking about how tired I am.
ANY tips? Should I try to exercise more for energy? Or just rest every chance I get? Any advice or words of encouragement would be so appreciated.
