If grandma had custody, and she does not trust the mothers care and wants to evict the mother, it does not explain why grandma was working out of town for 3 weeks. The babysitter clearly was not there for overnights. Working away from home for weeks when caring for 2 kids under 3 is something. I know there were other adults, but it does point to trusting the mother at least a little to care for the kids.I wonder what grandma was planning for childcare once the daughter was evicted, or whether working away for 3 weeks was not typical and she just did it this one time.If grandma has custody of the boys, that explains why there is a babysitter. If she didn't trust mom's care during the days, she would have them go elsewhere to a sitter while she (grandma) was working or busy.
