Agree with what ChocOrange has to say. Establishing a very short nap routine with DD (nappy, into grobag, blackout blind down, gentle song and a cuddle, then into cot) has got her from taking no naps or only in the buggy, to happily going down for a nap 2-3 times a day in her cot when we're at home.
Consistency is really important so even if it doesn't work for the first few days keep trying. And on the days it's a struggle, try taking LO out in the buggy for naps to make sure overtiredness doesn't set in as once they're overtired it's so much harder for them to settle down to sleep.
When I started with DD, I worked on achieving 1 nap a day in her cot to begin with (the morning nap), then built it up from there so it's not too much or too exhausting for you all at once.
You might find the naps are short to begin with (30-45 mins is typical). TBH I wouldn't expect much more from a 10wk old, but will probably still be tired which is where the buggy or a sling will be very useful).
Once LO is doing well with settling for naps, and a bit bigger, then you can work on extending them using something like Pick Up Put Down (Baby Whisperer).
But seriously don't stress if it just doesn't work for a while. It took until 12 weeks for my DD to be ready to start learning to nap in her cot. Best of luck x
