My babysitter just moved to the country a little less than 6 months ago and has not gotten a iTIN.
IN the end, regardless of weather they are a household employee or contractor, you *MUST* have their ITIN or SSN in order to claim the child care credit. Without the ITIN/SSN you can't claim that credit.
Moving forward, you should make it clear to anyone you pay to care for your child, in your home or elsewhere, doesn't get paid anything until they have provided you with a completed IRS Form W-10. https://www.irs.gov/pub/irs-pdf/fw10.pdf
