At 11 weeks DS had his daytime naps in teh pushchair, in the car, in his car seat, or in his bouncy chair.
If he didn;t go to sleep while "in motion", he would fall asleep on the breast.
He wouldn;t sleep lying down flat eitehr in his cot or anywhere else.
He slept for a maximum of 45 mins for most naps, sometimes a bit longer in teh afternoon.
I kind of fell into a routine where I would plan to leave the house at a certain time each day - say 9.30 - whetehr to walk to the local shops, or go further afield. he would nap during that time. Then he would sleep again around 12pm, in his chair, and anotehr late nap around 4.30pm, again in his chair.
At teh time I stressed about it loads but looking back it's not caused any problems at all.
He started napping in his cot around 5-6 months, and was fed to sleep for naps until he was about 12 months.
From 13 months he slept for 2 hours after lunch in his cot, in teh dark - and still does at 2.2.
I would say, go with teh flow. Do what seems to suit you both at this stage.
Plenty of time for him to sleep alone and settle himslef when he's a bit older
