You are the second person using this word ‘gundakh’…!!
I heard it for the first time from my husband when our daughter was born…
He was insistent that we ‘gundakh’ the baby…and that there is a technique to do it…
I never knew about it so used a receiving blanket or swaddling blanket but our baby always hated it…
she somehow was more comfy and slept well without having her arms all wrapped up…
