OP here. I would love to find a mother's helper, but have not been able to find one. I guess the idea of drop in care at a daycare wouldn't really work. I did find one place that offered it, but you have to pay for the whole day and it would be too expensive since we would just need a few hours.
The issue is if I have an appointment my husband has to take the whole day off, and he is using up all his vacation days. But with no local family, and since I can't find a mother's helper because it's hard to find someone who only wants to work a few hours a week, it's very hard to get appointments, etc. done when you're a stay at home mom without any local family.
