Am I doing something wrong????

My baby is 9 days old, and I feel like I’m doing something wrong. I keep seeing posts about clusterfeeding, but my baby isn’t doing that. He eats between every two-three hours, about 10-15 min per breast. He will root for more but when I put him back on the breast, he will just kinda play with my nipple and the spit it out. I assume he isn’t hungry anymore and just wants comfort, so I’ll give him a paci and lay him down for a nap. Sometimes he wakes on his own for his next feeding and sometimes I wake him. He has around 7-8 wet diapers a day...is this ok? I’m just scared my babe isn’t eating enough. 😥
