I have tonsillitis but my 2 year old son keeps grabbing my drinks and drinking it!🤦🏻‍♀️ how likely is it for him to catch it?

So I put my drink far back in my tv stand & he climbs the dresser to grab my drink and he’s suuuuper fast about it, I turned my back for only a minute and he was already drinking my drink.

I just started taking medication today & I’m really concerned he will catch it from drinking from all my drinks

First things first I have white pockets in the back of my throat and it’s swollen, say if he does catch it, will he have white pockets as well? I want to make sure I’m able to detect it

And second question, how likely is it for him to catch it? He’s only 2 years old and it just scares me

I also still breastfeed him I don’t know if that matters or not
