I wish I could afford daycare

So I am very fortunate to be able to have family come into my home throughout the week to care for my children. Someone comes at 1:30 when E goes to work and I get home at 4:30 and for the most part it works wonderfully. There are some sacrifices to be made, but the benefits outweigh them. Except for on nights like tonight.
My boss has passed away. She fought a long hard battle against cancer. Let me tell you, she gave it a run for it's money. Her wake is tomorrow after work adn I don't have a babysitter. My mom is "the person" for Fridays, but E has had fridays off for the most part, which is good because my mom has been ill. (Whole other story there). So here I am with no babysitter and I won't be able to attend the wake of the woman I have worked for for 9 years. The woman who has been my only profession boss. I am so sick over this. My stomach is in knots. I am still holding out hope. Someone usually steps up to the plate. I know if any of the other family members can watch the kids they will.
