The organizers asked me to advertise this and I sympathize:
We are pleased to announce that we will provide pooled, subsidized child care at STOC 2018. The cost will be $40 per day per child for regular conference attendees, and $20 per day per child for students.
For more detailed information, including how to register for STOC 2018 childcare, see http://acm-stoc.org/stoc2018/childcare.html
