4 month old making gasping noises

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊
So for this past week I've noticed my 4 month old making this random noise as if he's gasping for air. He does it while laying down.. Laughing and I notice it more when he's wining. I'm a first time mom and I'm trying hard to learn that some things are just him growing and changing. Has this ever happened to anyone else?
