Depends a lot on the climate of the school. I think kids at this age largely follow the lead of the teacher. The one of mine that did this was in the school PT through 3rd grade, and really didn't have any issues at all socially. But the teachers were very matter-of-fact about it, didn't make a fuss or comment on it unnecessarily, and went out of their way to let me know if some special project, activity, or field trip was going to occur on an out-of-school day, so we could consider an extra day that week, or switching our in-school day. We had administrative backing, which helped tremendously. I also made a point of involving myself in the PTA, any in-class volunteer opportunities that I could fit around my work schedule, etc.
