5 month old choking on saliva?

Payton

So today I had two scary incidents with my LO. Both times she was laying on her play mat.. she would start coughing like choking on spit. I pick her up and she's having a difficult time breathing for 30 seconds to a minute. Also tears running down her cheek. But when it's over she's fine. I'm wondering if it's normal? If not I'm calling the doctor tomorrow. I'm just scared, first time mom here. 🤧
