Newborn care anxiety

My daughter is 3 days old and I have a 3 year old son. I can’t shake the feeling that I’m doing everything wrong.

She slept 3 hours in her Basinet last night then the rest I kept her in bed with me pretty much nursing the entire time. Today she’s slept pretty much the entire day in my arms. She nurses great so I’m happy about that but how much sleep is too much, restless sleep at that. She must be on or right next to me.

Can anyone relate??
