This does not have to be formal training, but should include basic parenting skills. Often relatives are a low cost or no cost alternative. Of course, many parents do not have this choice available, lacking a relative that lives nearby with the availability to care for their children. A relative may care for your child either in your house or theirs. When choosing a relative for childcare it is important to lay down groundrules so that the relationship between the adults does not become impaired by childcare issues.
Respect is an important factor.
She must respect your parenting ideals, even if they are different from her own. In return, you must respect her and not take her position as caregiver lightly. You must remember not to take advantage of her family position and take her for granted. You must treat her the same as anyone else looking after your child and maintain time arrangements and not expect her to care for a sick child. Relatives may be available for odd hours of care like shift work and part time care, and may be able to care for your child if your job involves travel.
