I say, and with God's success: The vow is not to be consumed by the one who makes the vow or their children, but rather it is for the poor. If she intends the vow, she must slaughter it and give it to the poor. If she intends the image she mentioned, this is not a vow, but rather food for the family only, regarding the amount that the family eats. The amount she intends to distribute to the poor would be considered a vow, so she must give a portion to the poor, even if it is money. And God knows best.
