I don't know if this is an issue or not for your LO and your kitchens.
Remember the story I posted about someone's child opening the oven door and crawling into it while it was hot!? Of course the mom reported some severe burns and the trauma was enough to make me worry when that day was coming.
Our oven is a wall mount and it under the cabinet. Such a crazy design! When I am old I am going to have a heck of a time bending down, getting large casseroles, etc out of there.
Thank goodness we just replaced our old oven with this one. It's amazing that the door isn't even warm to the touch when the oven is on full blast.
Anyway, just wanted to say that I tested out this device and it works, in case you need one, too. It was only $4 at Walmart.

It works by adhesive on a metal plate, sticking to the roof of the space above the oven's door. Then the latch comes down at 90 degrees. It's so childproof to open that DH needed my help the first couple of attempts.
