How do they welcome a new born baby in Hindu?

Answer 1

As soon as the child is born "Jatakarma samskara" is performed where the umbilical chord is cut and the father welcomes his new-born

child into the world, while praying for his long life, intelligence and well-being, and feeds it with honey(2 grams) and ghee (clarified butter)(1/2 gram) on a gold

ring while reciting a sacred mantra (chant) in his right ear. This ceremony can also be performed by another member of the family if the

father is not present after consulting with the family priest.

The ghee and honey cleanses the child's digestive tract by assisting the

newborn to pass meconium and also nourishes and strengthen until the first breastfeeding takes place

so, the ritual is ancient with lots of consideration of scientific facts...

Answer 2

usually babies are welcomed with grabha sanskara (baby shower). While after birth there is naming ceremony of the baby. After that saint come and bless the baby.
