I know you're normally supposed to keep the nursery between 65-73 degrees. If the baby is getting sick or is sick, should the room be on the cooler or warmer side? We went to a playgroup on Friday and every kid had huge rivers of snot coming out of their nose and coughing with wide open mouths. I know LOs getting sick is inevitable, but if your LO is sick, keep them home. Don't go out for your own selfish reasons.
