If you are sleeping the whole day you won't be tired at the evening. That applies to your baby too. Too much napping is not good.
It's absolutely right that babies need first lots of sleep but when they grow up a little bit they need to learn the difference between day and night.
I didn't let my babies sleep in the late afternoon otherwise they would't be tired to sleep at night. When I felt they are to tired to stay awake they slept for half an hour before I woke them up again. I didn't use the stroller because my babies loved to sleep in their strollers. Instead of taking a walk I played with them to make them really tired for the night.
