While I don't have a research article, I do have practical experience in this
matter.
My firstborn (1980) weighed in at 8pounds and slept through the night from
the age of 5 days.  It was relatively soon that she slept 12 hour nights.
But, she nursed all day long and slept very seldom during daylight.  She did
sleep at bedside in a bassinett until 3 months, then mostly shared our bed.
She was a VERY high needs, high touch child when awake.

My thoughts are, "if it ain't broke, why fix it?"
