Well, in the blink of an eye, Jenelle's little one has already zoomed through that stage and now he's in that absolutely percious smiling, laughing, not a care in the world phase.
In this sweet video that Jenelle shared, Nathan is popping out at Kaiser and the little one thinks it's the funniest thing he's ever seen, which might actually be true because he's only a few months old so he hasn't seen too much hilarious stuff.
Yes, of course people got mad that it looks like he might be scaring the baby, but Kai doesn't seem fazed at all and if he was terrified, he probably wouldn't be cracking up like that.
In a second video that the reality star shared (below), Nathan was "head bumping" with Kaiser and it's so sweet how Kaiser quickly catches on to the little game and is all about it.
