Am I a bad mom?

So yesterday was one of those days where as soon as Shawn walked in the door, I threw my hands up and said I'm clocking out. Inara and I went to a park playdate with the moms group. I had a great time talking to a couple of moms I haven't had the chance to talk to much. Inara had a fun time playing with the kids, especially in the sand play area. She started getting fussy because it was time for a nap, so we headed out and she fell asleep on the car ride home. When we got home, I placed her in the crib and she crashed for about an hour. When she woke up, boy did I feel like the world's worst mom. I hadn't even considered the possibility of this happening. When I went in to get her, I noticed her crib was covered in sand. What the? JACKED!!! I scooped her up and started taking her clothes off only to find sand sprinkled all over her body, even in her diaper. Please explain to me how does that happen! I know she fell in the sand once, but she had a long sleeve shirt on, socks and shoes, and pants, so how in the world did she get sand in her butt?

Anyways, I got her changed and let her run around upstairs after I closed off the hallway with the gate. I then proceeded to clean up her changing table, which now had sand on it, and brought the vacuum up to clean her crib. For my second surprise, my vacuum wasn't working. So I went and got a new bag, cleaned the vacuum, and tried again. No luck. Mind you, this whole time Inara is up in my business because she can't be more than 5 inches away from me most of the time. So I realize I'm going to have to take off the crib sheet without spilling sand all over the place. With my bad back, I can't pull the crib out from the wall to get the damn bumper pad off. Yes, I said damn. So I finally get the sheet off the bed. Gather up all the dirty laundry and Inara, and we head downstairs. My luck, one corner of the wad of stuff comes undone and sand starts trickling out as we're heading downstairs. Just great! So I now have spots of sand in her room and on the stairs and no vacuum to get it up. Oh and Inara had a nice little rash at the top of her diaper area around her waist where sand must have been rubbing on her when she was sleeping on her belly. Ugh! I now understand what a "Calgon take me away" day is.
