It is not advisable to slip down the stairs and break your shoes while your pregnant. For one, in just a week I will be three months from my due date and despite the fact I have put on exactly zero weight I am starting to drop things and wonder if it is really worth picking them up, or I attempt to pick them up with my feet. So falling on my back often means I do a gaara impersonation (see above picture).  Putting on shoes is something that must happen sitting down, or I will lose my balance and fall, I am not dealing well with the center of gravity changes.
Last night my darling and I were headed out to go buy video games to keep me entertained. We reached the front of our building where the stairs are steep and about 90 years olds. I walk these steps generally twice a week (the only times I leave our building), and have never had an issue with them, but as my womb moves up over my belly button and begins to reach my ribs, my balance is lightly off. I slipped last night, one moment I was perched at the top of the stairs the next my entire body was lying across the stairs. My feet poking through my sandals which had ripped under the entire weight of a twenty year old pregnant women. Poor shoes had served me well since I broke my previous sandals (which were much easier to get on) a month before by tripping on the curb. My back which took the impact of four stairs was aching, and my knee which I attempted to stop myself sliding with also ached.
So instead of getting a video game we trotted down the block to number one shoes to pick up a new pair of those before going to the video game store, and to get me something cold, so I could make sure my little guy was okay. He is, frozen coke really did the trick. He kicked right up till we went to bed.
I woke up this morning with what I suspect are bruises on my back, and pain still evident. Oh dear, don't fall down stairs when pregnant ladies, it hurts.
