Sleeping issues

Hi mommas I need some advice. My baby is 7 weeks old. He currently will only sleep in the rock and play. He will do a 5 hour stretch, eat, then another 2-3 hours. I feel so guilty that he will only sleep in the rock and play. I don’t even turn it on. I try to get him to sleep in bassinet and even recently have tried to do naps in crib. As soon as laid flat he instantly wakes up and will spit up. He does have reflux and I keep him up right for 30 minutes after Bf. He hates being swaddled. Bassinet does have wedge to elevate his head. Just wondering if anyone else has had this issue.
