Don't let them go to sleep so early

Stewie goes to bed between 1030 and 1045 every night (like clockwork). He eats right before bed at around 10PM and doesn't wake up until I do (sometimes as late as noon or 1PM). I have a pee pad in my room that he may jump down to use in the morning, then he crawls right back in with me.
I think he sleeps so late for a few reasons. One being that he sleeps with me in my bed, so he's not in his crate worried about what I'm doing or if I'm awake -- he can see that I'm asleep. Second being that he eats later so he doesnt have to wake up as early to pee/poo. Also, I run him around as much as I possibly can and keep him from napping.
Hope I helped a little!
