If she intended to make `Umrah but her little kids kept her busy and she forgot to do so, she is supposed to slaughter a sheep which must be distributed to the inhabitants of Mecca.

 

This is based on the hadith of Ibn `Abbas: The Prophet made Dhul-Hulaifa as the Miqat for the people of Medina; Al-Juhfa for the people of Sham; Qarn-al-Manazil for the people of Najd; and Yalamlam for the people of Yemen; and these Mawaqit are for the people at those very places, and besides them for those who come thorough those places with the intention of performing Hajj and `Umrah; and whoever is living within these boundaries can assume lhram from the place he starts, and the people of Mecca can assume Ihram from Mecca.
