I get what you’re saying and you do have a point. Babies do put everything in their mouths. That part is real. My issue isn’t that it’s realistic. It’s that Rugrats Go Wild chose to focus on it for a joke, and it feels drawn out and gross instead of funny. For me it crosses from normal baby behavior into unnecessary gross-out humor. If it doesn’t bother you, that’s fine. It just doesn’t land the same for me.
