These worked really well for me: https://www.amazon.com/dp/B0C535GDH3?th=1 My husband used purchased wood screws for the wall rather than the ones included (he didn't trust them) but the bracket to shelf screws were OK. And you might be able to get a lumber yard to cut a sheet of plywood or MDF into like 10-12" strips? Wood lumber tends to wonk/cup (and wide boards are expensive) and shelf stock can be expensive. Another option is to secure a free-standing bookcase with an anti-tip strap (I think a lot of "tall things" come packed with them nowadays) and put like fabric storage boxes on the lowest shelf and then face the books right to the edge on the upper shelves - wold toddlers see that as a solid wall rather than rungs to climb? IDK.
Wow, a two rod closet? This is the second goofy closet I've seen today. In season clothes on the front rod, out of season clothes on the back rod? Or everyday stuff in front, specialty stuff in the back? Another thing you could try is to take better advantage of the depth by removing the rods at the back and replacing then with a rod mounted on either the left or right side (whichever has more space between the door and the corner) - essentially making the closet a walk-in. You'll probably need a longer closet rod than the two you have. If the closet is wide enough, you might be able to have a rod on both sides (but I'm guessing from the photo it's probably not). You could keep the shelves you have but I would be tempted to move those as well. Add brackets above the new rod. It looks like the shelves you've got are two boards put together to make one wide shelf so you might have enough material there. (I had really good luck with these, but you would probably have to find at least two studs). You can always put a folding step ladder in the closet to reach the shelves. Things would be more accessible and you could add some hooks on the back wall for bags, etc, maybe even a shoe rack and/or bins for off season storage underneath the hanging clothes.
