Raspy cry?

For about a week and a half now, my son sounds so raspy when he cries!! He’s acting totally healthy & normal, and when he babbles he sounds normal.

It’s just when he cries, it just sounds different than normal, mire hoarse like..?

Could it be allergies or something? I feel like it’s not worth taking him to dr just with covid going on especially since he’s acting normal and happy.

Thoughts?
