Two week deposit..

[skyee]

Hi Ladies,
Well I decided to post as I have a question to ask. I signed with a new family last Aug for a Jan start. I usually ask for two weeks deposit which goes towards the first two weeks of care. I have a document that both signed that I received the deposit and its non- refundable if they decide at the last minute to not put their child in my care. The thing is, my first day with the child was wow! She screamed for 4 hours straight,outdoors as well she screamed the whole time in the stroller and I go to the bus to drop off a boy, she didn't want to be held, or drink/eat it was heartbreaking to see the child go through that...it was hard on my other children as well....for a whole 2 weeks.
How much time should we give a child to adjust? and the parents want their deposit back, but I actually cared for the child.
