My nearly 3 yo twins seem to get colds, coughs and other junk easily. They are both on their second cold/cough/fever this month! It feels like they get better for like four days and then one gets it again, followed by the other. There has been one or the other sick with only brief breaks since the start of November...it feels like every year it's like this! For like five months. One got tubes put in in early December but has still had two colds/coughs since (no ear infections though). Any advice? Or commiserators? My mom thinks it's really weird that they get sick so much.
