Quoting Onalee's Mummy:" Well if you went to work she would then have to pay daycare. It's not fair she gets free childcare n ... [snip!] ... struggle. I would start your own daycare and ask her to pay full price if not look after 2 other kids whose mother will pay"
I agree with this....
Have you tried hiring a nanny? They tend to be cheaper and sometimes can be much better than daycare.
do you qualify for assistance?
and your sister/sister in law, whatever, should be supplying food for her kids at least. i'm all for helping family.. but.. the situation isn't helping you.
