I'm really shocked that some people are that cavalier about thinking one can just drop their kids off anywhere and "find" care . If I had to start sending my 3 and 5 year olds to a random drop off daycare that they didn't know or I didn't know, that would be a major problem for me and them. And "having a friend" do it is not as easy as it sounds....I have plenty of classmates of my children that I am friendly with, but none on whom I would impose like that. And just because your kid might go to school with someone doesn't mean they play on their soccer team, etc.
I have been called a few times and have been fortunate that I was able to defer for two years each time. The first time, my dd was an infant and I was working- her caregiver and the court where in opposite parts of the county and I could never have managed to get her dropped off and get to the court on time, nor could I have picked her up on time if I had had to serve. The next time, I was the SAHM mom of a 1 and 3 year old with no childcare,no family in the area to pick up the slack, and the next time, SAHM to a 3 and 5 year old. Again, I explained the situation and was excused for 2 more years.
I don't think that it is easy for any mom, but now that I am a working mom, I know it would be easier...I have options since my kids do have caregivers, and before and after care options at school, that I didn't have when my kids where younger and at home with me and me alone.
My plan, if I had had to go, was that I would bring the kids with me...since I had no childcare I had no place else to leave them, and I figured that would illustrate the point!
Good luck.
