9 week old sleep schedule help!

My LO is 9 weeks old and so we have mainly been following his cues for sleep so far. He has wake windows during the day of about 1-2 hours. We tried implementing a night time routine for a week or so but if he wasn’t “ready” to go to bed yet, he’d just count that sleep as a nap and be awake after for another hour. So we just let him sleep when he gives us cues and go to bed with him when we go to bed. He does still wake up every 2-3 hours to feed so I don’t think we get a real consistent routine for his sleep yet.

The thing I’m wondering about is his mornings. He wakes at 6 or 7 to feed and we change his diaper but then he immediately goes back to sleep. Sometimes he’ll do this multiple times and be sleeping until 11am or noon. Is this normal or do you think this is a continuation of his sleep and keeps him from having a set bedtime early enough at night?
