she's fine, thanks for asking! i sleep with her and she stirred to nurse twice overnight like normal and in the morning was her usual self. yesterday right after it happened, she clearly identified that her "head" was hurt by the fall down the stairs, but by morning, when i asked her what part got hurt (i asked while we were walking down the stairs together, holding hands), she listed leg, elbow, teeth, head (there was no blood or anything at all, so i don't think her teeth were really impacted, i think she was perhaps listing it all b/c she did effectively roll down, full body impact-- but in any case, there was no serious harm done). her eyes looked normal right away.
whew! i feel like we got really really lucky. i had my husband reinstall the gate at the top of the stairs, so i have more control over when she heads down. i'm also reminding her a lot to be really careful, hold the railing or go on her butt or her stomach to go down.
to make matters worse in terms of logistics here we've got workmen adding a new section of rooms upstairs and they've laid out plastic carpet covering on the stairs and the carpet in front of the stairs, which DD loves to run on. it's not *especially* slippery and i'm making sure she's barefooted in the house to give her better traction, but i'm just like more paranoid than ever, seeing her fall like that was such a helpless feeling and i do thank god that she went down the way she did, it could have been so awfully worse, and i really really don't want to have a repeat accident with dire consequences.
ugh, stairs. i really wanted them when i bought this house, i wanted an upstairs, and i still like the upstairs. but with a little one, they are dangerous.
