At this point, I don't even know.

Voldemort glided into the Potter's home, smirking.

Today would be the day he would destroy Baby Potter, proving that he was invincible.

He paused. The whole family was upstairs, in the nursery, playing.

He sneered. Pathetic.

He started up the stairs, and had just reached the top when-

He bumped into something.

The thing looked like a gate, only smaller, and not wooden. It was some sort of Muggle material, pastick or something.

He growled in frustration when the thing refused to budge.

The Potter adults walked out of the nursery at that point, wondering if Sirius got stuck on the baby gate again.

Close, but not quite.

Lord Voldemort, immortal dark wizard, half blood, was finally stopped by a… baby gate?

"Um, you lift the-" Lily started.

"Yeah, you lift the thing-" James said, trying not to snicker.

This continued for a while.

"You know what?" Voldemort said, throwing his hands up in frustration. "I'll come back when he's older. Floo me when he's ten or something." He muttered, and apparated back to wherever dark wizards went when not trying to find noses, conquering the world, or being stopped by baby gates.
