From what I gather whooping cough is going around our household, I have little ones, 1,3,5,7,9 years of age. My 3 year old is waking up during the night almost as if she catches herself not breathing and is gasping for air and coughing. She has been having this now for 3-4 nights, she’s fine once she takes some deep breaths and goes back to sleep and is fine during the day, although she might have a hacking cough here and there. What should I give her to help her with this?
