Question for the parents or uncles and aunts..or anyone around kids i guess

So my little one is 2… His vocabulary is rather ridiculous he knows dinosaur proper names…complete sentences… Can count to 50 most of the time without forgetting any numbers…ect

Anyway my gf, her grandma and I have an ongoing bet to see who he will say I love you to first… He refuses and very adamantly to say love to anyone or about anything… He’s very affectionate and kind passing out hugs and kisses like he’s running for office lol… He’s the first one to ask if your OK when you seem sad or injured… Followed up by an I’m sorry it will be OK and a hug or comforting shoulder pat… But he refuses to drop the L-bomb… What’s up with that?

It’s almost like he knows we want him to say it and is pulling a prank on all of us and remaining silent… he picks and does things he knows will make others laugh and has the worst poker face while doing so idk…thoughts?
