My toddler keeps coughing

Yeli

High y’all, I have a question…

So my son has been one to cough when he’s very active. I’ve never thought anything of it because he a kid and their bodies are still getting acclimated to life. Anywho, I’ve notice that now his cough is at night while sleeping and when he wakes up. It’s becoming concerning. I saw his doctor and he said he is fine, however, I just don’t like seeing my baby like this.

Have any of you dealt with this? Any advise?
