my puppys routine sounds about the same. he will get up and eat breakfast and some times he dont want to eat like today and thats fine. they will eat when they want to and he will play with me in the mornings and then use the potty and he will then usually lay down and nap in the after noons. and thats ok. it is good for them to nap its helps them not get so drained and want to sleep all day. puppies play hard and sleep hard. I would be more worried about not eating then sleeping.
But he will play with me at any time. If he just layed in his bed and did not want to play when i intitated play time then i would worry about that to. But he is just tired it sounds like to me.
