I work from home occasionally and have a 3 year old son. I also allow some of my staff to telework. I think it is a reasonable question to ask about child care. At my company one would not be allowed to work from home if they did not have child care - it's unreasonable to expect someone to be able to work full-time from home while also taking care of a child. I think the manager should have come to you personally though and had that discussion.
