Baby is sick, but I feel like I go to pediatrician a lot, should I go?

Hi, I’m doubting if I should go to the pediatrician for my baby’s symptoms. I feel like I go to them a lot and I don’t want them to think I overreact. I am a little of a hypochondriac myself. I am afraid that if I go too much they won’t take me seriously after a while.

These are his symptoms:

He coughs a lot

Mucus

He shrieks/cries loudly, as if in pain, after coughing (this is what worries me the most)

He scratches at one ear a lot (he doesn’t have a fever though so I think no ear infection )

He is weirdly sweaty, particularly his forehead

He sleeps bad (3hrs at a time, at night)

He uses his, what I call, Sméagol voice a lot. It’s a raspy voice in which he babbles. I feel like that can’t feel good on his throat.

Important: no fever, normal drinking and eating, normal diapers, still active, responsive and smiling.

Should I wait it out?
