Baby proofing ac outlet?

I have a 20 amp outlet for a ac unit under the window in my living room. It’s a open space in front of it. My lo started to crawl like she’s been doing it right out of the gate. I placed the covers in every outlet she can post get too all except this one. A standard outlet over won’t fit. I even ordered the box cover thing I could just cover it like that but the outlet and the screws to instal it are even different. Anyone have any ideas or know where or what to look up to find one that would work with this? Do I have to take the outlet out and just cover it with a plate? Idk want to mess with it that much.
