Sorry but I will not continue a nonsense argument that has no basis in tax law.
It's the grandmothers income, not yours, and she must comply with tax law.
Refer to IRS Pub 17
https://www.irs.gov/pub/irs-pdf/p17.pdf page 44 for the rules of child care providers and babysitters.
Childcare providers. If you provide childcare, either in the child's home or in your home or other place of business, the pay you receive must be included in your income. If you aren’t an employee, you’re probably self-employed and must include payments for your services on Schedule C (Form 1040 or 1040-SR), Profit or Loss From Business. You generally aren’t an employee unless you’re subject to the will and control of the person who employs you as to what you’re to do and how you’re to do it.
Babysitting. If you’re paid to babysit, even for relatives or neighborhood children, whether on a regular basis or only periodically, the rules for childcare providers apply to you
