Cough

Anyone’s little have a cough before? Mine woke up this morning with a cough...I called the baby nurse and she said maybe teething (she is super slobbery and chewing on everything) or the weather change (AC to dry central air heat/dust from the winter). She is very much herself and content (just usual bedtime melt down lol). But I’m so worried it’s something more...reading all these RSV posts has me sooo paranoid! 🙈🙈🙈
