Newborn and husband

I have a 3 week-old baby and my husband seems to be a little distant.

He was great during the first couple of days, and i know he loves me and our baby boy but I don’t understand why he is acting cold towards the baby.

He holds him for a few minutes and then gives him back to me.

I need help, as a new mom I’m so tired but I’m also worried about their relationship.

Do you guys have any advice?

Thanks in advance.
