Interesting.
I am up at 5am, spend some time with Rocky, leave food for him and leave home at 5:30. He goes to sleep after that according to my parents and wakes up around 8 along with them. Runs around like crazy, plays with toys, then goes to my room at around 10 and naps till I come home at 2-3PM. then he is with me most of the time, or goes to his bed to nap a little. On weekend we go walking the moment I open my eyes, at 7am. So he gets plenty of time on weekends. Plus I take him with me on drives and nature outings.
On days that I will be gone for more than 8 hours, I send my dad to hang with him for an hour, he would be happy to.
It's just so unbearable to know that a little one is sitting at home waiting for you to come home.
