What is the difference between puṁsavana, sīmantonnayana and valaikāppu?

puṁsavana and sīmantonnayana are Vedic saṁskāras of pregnancy; valaikāppu is the South Indian bangle ceremony often done with sīmantam.

The Gṛhya Sūtras describe two saṁskāras during pregnancy. Puṁsavana, in the early months, is a prayer for a healthy child and safe growth. Sīmantonnayana, usually in the 4th to 8th month, means “parting the hair”: the husband gently parts his wife’s hair, prayers are said for her well-being and peace of mind, and music is often played. Its heart is care for the mother.

Valaikāppu, popular in Tamil Nadu, is the women’s celebration where glass bangles are slipped onto the mother’s wrists, believed to cheer her and the baby with their sound. Many families combine it with sīmantam on one day.

Today most families do one combined function rather than all of them. Any of these, done simply with a pūjā and blessings, is meaningful. The sex of the baby is not the point; every child is a blessing.
