Ya - siblings are a mixed blessing in the beginning they fill TWO spots which is awesome but than they make up 2/5 your income which sucks when they leave!

I do not give sibling discounts ... children are not a 'bulk commodity' it does not cost me LESS to provide care or service to them just cause they are related and as mentioned above when they leave they are a liability of loosing 2/5 your income at once

I do find that caring for siblings can be a mixed blessing depending on the kids personalities ... for some infants having the older sibling makes transition 'easy' cause they see them having fun and feel at ease and trust you faster - for others having sibling here they follow that sibling around crying at them and ruin the older siblings fun during the day or the older sibling bosses around the younger one or the other kids about their little sibling and you are dealing with telling them 'give your sibling space' and you end up with TWO miserable kids to deal with.

Currently I have two sets of siblings .... and they are night and day as to how 'enjoyable' siblings can be one set is awesome with each other the other bicker like cats and dogs and I have a calendar counting down the days until they are both in school full time for September cause the loss in income will be the least of my worries after 8 weeks of full time summer with both of them if I am not found in the fetal position in the corner one day begging for a padded room and some QUIET
