What can I give my toddler for stomach ache?

Jullz ☀️

My son just woke up and he says his stomach hurts. He’s 19 months. All I have for medication is for cold symptoms. I will run to the pharmacy if I have to but what can I do? He’s been fine all day, maybe eating a little bit less than usual. No change in stools or issues with it. He’s crying and wants to be held and doesn’t want to go back to bed...
