Nap times

My baby boy is 7 weeks old and his sleep is all over the place. He generally sleeps very well every night but his naps in the days vary. If we have a busy day and we are out and about he will sleep the whole time but if we are home he will stay awake for hours and hours and only have about and hours nap all day. When do I start a nap routine and how do I go about it? 🫠 Also he will only ever nap on me, how do I start getting him to nap on his own? Or is it too early for this? Thank you in advance 🤍
