Napping with one month old

My son is 6 weeks old. He hates sleeping in his bassinet and won’t sleep very long if at all during the day, ever. Sometimes 2 hours at night if I’m lucky. Today I breastfed him in my bed and he fell asleep for 3.5 hours with me. He was on his side because of feeding but stayed tucked into me, I had a blanket up to my waist but not near him and a pillow behind him in case he rolled over. Is this dangerous? I just cuddled him and watched a show I didn’t nap as well, but I was thinking it would be an amazing way to get some much needed sleep.
