But as some adults are rewatching their nostalgic favourites, they're discovering some facts that they never picked up as kids.
The fact has had people realising the emotional backstory of Tommy's protective parents, and relating it to their own children.
"Crying as I am pumping right now for our daughter born almost 10 weeks early and currently 3 weeks into her NICU stay..." commented one new mum.
"Damn. And now I'm crying. Our babe was premature and I hate to think he was looking for us when we couldn't be there," mentioned another mum.
"As a kid who grew up watching Rugrats and the dad to a micro premie who spent 95 days in the NICU this definitely made me tear up a bit," commented a dad.
"No wonder why Stu calls him champ, why DeeDee is always worried about him, and why Tommy is always so brave and doesn’t take life for granted."
