So, going on maternity leave in the fall, coming back in February. Am planning on pumping during recess and lunch. My concern (which hopefully is shooting far too ahead) is about four students of mine who struggle with getting out to recess and staying there. Two I'm pretty sure just want to sit in the class and chat with each other and play--these two will get passes from the paras to come in for a drink/bathroom... and then try to get into my classroom. One kid is autistic (high-functioning with all of 2 mild accommodations) who is fixated with books and likes to pop in during the middle of recess to switch books. One legitimately struggles with learning and social schools (with her past teachers and the counselor also noting she often play the helpless card on top of everything) and every so often has been coming in for comfort. There's a smattering of others who will try to come in now and then, but those are my four big offenders. I'd like to get those four really prepped on going out to recess and staying out there so I can pump (the school at this time just doesn't have a separate place other than the individuals classrooms--which seems to be the preference so far--for pumping). My admin has told the other pregnant teachers (we are many) to put up a sign and lock the door, but these are second graders I don't want mobbing about the door in desperation during recess. I also don't want them pestering the paras needlessly to come in. Any ideas on getting my kids used to the idea of going out and staying out?
