My baby makes this very worried face and kind of like gasps for air/looks like he is about to cry and then settles.... is that normal?

We noticed it first when we would put him in the bath he would have this big reaction and then calm down. But I’ve noticed him do it a few more time when he is just laying on his back and I’m talking to him/playing with him. It seems to be like an involuntary response to being like surprised or excited? But I’m not so sure.

Can anyone relate to what I’m describing and if so what is it? Any advice would be appreciated!
