Yes, OB does not have an applicator. I actually like them, they are Moore comfortable because yippy can get them better positioned, and they are able to hold more. All of the tampons with applicators were extremely uncomfortable, and I couldn't really use them. Daughters thought not having an applicator was gross, but to each their own.
Around here, anchoring things to the wall whenever possible is a necessity, as we do occasionally shake, rattle and roll, though not as much as California. It's been a while since we had anything we felt, like 17 years, and nothing that did any damage to us, although some facades in the downtown Seattle, Tacoma and Olympia areas were damaged.
I strongly suggest a corner for the bed, as well, and then anchor in the corner (you can anchor the leg near the bottom of the mattress frame) and again as close to the other two corners as the studs allow on both walls. Please anchor the bed frame, where the mattress sits, for the the other two corners, not the side rails that keep him from falling out. It's more sturdy than the rails and legs, and it gives you more opportunities to anchor safely.
