Please help me, help my baby nephew...

In the last 24 hours I have become the temporary guardian of my 2 and a half year old nephew. It happened unexpectedly and out of nowhere, but I refuse to let him go into foster care to live with strangers. Since it was with no notice that I would now be his guardian and going from a childless adult, to a full time Auntie ( I'm not gonna call myself his mommy cause he knows me as his auntie and that's what I am) I literally have only the diaper bag he came with. I have a job but wasn't prepared for this situation and don't get paid til Friday. And unfortunately the items in his diaper bag just won't last that long. Anything and I mean anything helps as I will be forever grateful and any help will mean the world to this sweet loving little boy and myself in this time of need and big changes in life for him. I have attached my PayPal link if anyone is so kind as to be able to help us.
