The ritual of first seating of child on the ground is known as Bhumi Upaveshana and it is an important Sanskara in Hinduism. The time when child is first seated on the earth is considered very significant for the physical growth and well-being of the child. Usually, it is performed in the 5th month after birth. Following considerations should be looked into while choosing an auspicious time for Bhumi Upaveshana.

Kati Sutra Dharana i.e. wearing of cotton thread around the waist is performed after worshipping the Mother Earth and Lord Varaha (an incarnation of Lord Vishnu) and the child is seated on the ground.
Aajeevika Pariksha is also performed during Bhumi Upaveshana. During it, a number of articles like gold, silver, cloths, knife, books, tools, pen, toys, etc. are put in front of the child and whatever article the child picks up, decides the means through which he will earn his livelihood in future. Few people perform this ceremony along with Annaprashana itself.
