I am not a lawyer, and the legality of providing child care for a disabled grandchild while the biological mom is away on vacation can vary depending on the jurisdiction and specific circumstances. Laws regarding child care, custody, and guardianship can differ between countries, states, or regions. Therefore, it's essential to consult with a legal professional who is knowledgeable about family law in your specific area to get accurate and up-to-date information.
In many cases, family members, including grandparents, may be allowed to care for a child, including a disabled grandchild, during a parent's absence, especially if it's done with the parent's consent or as part of an agreed-upon child care arrangement. However, certain legal requirements, such as obtaining temporary guardianship or custody, might be necessary in some situations.
If there are any existing custody arrangements or legal guardianship orders, it's crucial to follow those guidelines and obtain appropriate permissions before providing child care. If you are uncertain about the legal implications, it is best to seek advice from a family law attorney who can provide guidance based on the specific circumstances and local laws in your area.
