Even moms enjoy playing and it is important to have normalcy in their lives and fun. It's easier to strike balance for them when the pups are older.
When they are younger, moms do not want to leave their pups so I still take them out, weigh the pups and give them a full body massage where they stick out their tongue in appreciation. They do tell you when they like something and each day I try to make sure they have that expression at least once and shoot for many more.
When they are happy, I am happy.
