It definitely sounds like she didn't quite know what to expect, and isn't cut out for this job. Have you asked her if you could have the deposit returned so that you can use it towards a new arrangement so that your son does not have to return to her next week? So that she can spend quality time with just her daughter before she returns to work? She might actually feel relieved and just give it back. If she is not, I would just continue to send your son there for the remaining 2 weeks if you feel he is in good hands there, and use this time to not feel SO rushed in finding a new childcare arrangement. Hopefully, the next one is a better fit!! Good luck!
