Whooping cough?

Tiffanymtoma

My LO is a month old and has developed this cough. It usually wakes her up out of her sleep and it’s hard to describe but doesn’t sound like wheezing (more like choking) I took her to her Ped today and they checked her lungs, said it was probably a dry cough she got and nothing to be concerned. Now that we’re home, I’m worried again because she’s coughing. She wasn’t coughing at the docs office, it’s usually when she’s sleeping. She’s also sneezing and congested which they said to just do saline drops. Any advice is greatly appreciated as I’m just worried and can’t sleep .☹️
