Kuro was asleep for all of Boruto's pregnancy,since Boruto's energy was diverted to the growing baby,and when he woke up,first thing he saw was a small,chubby human. He was confused at first,but seeing Asahi's smile was all he needed to love him.
And Boruto,being a new "mother",is a bit too cautious because he knows how strong Kuro can be.
