Hi. my daughter took a tumble down our stairs a few days ago. she is not quite 18 months, weighs about 21 pounds, and is roughly 2 1/2 feet tall. we did not realize she was able to open the door to the stairs. she did not roll head to feet, she slipped and ended up sideways and actually rolled down the stairs (like you would roll down a hill). They are carpet and heavily padded - and we had just tossed several blankets downstairs (this is what she landed on -on her back) we were racing down the stairs behind her but just couldnt catch her.. it appeared to me almost as if she floated down them, it didnt seem as if she even really touched the steps. she cried right away, but within 10 minutes or less she was up and running around and playing as her normal self. (She started giggling as we were in the van on the way to the ER - and we both looked at eachother and decided to go home and watch her) Her pupils shrink with the light evenly and well... she hasn t been sick, or had any change in behavior. she doesnt have one red mark on her anywhere to indicate she hit anything.. however she does have one scratch (rug burn kind of) on the corner of her eye, and her eyelid turned a little pink the next day but is already looking better. was slightly swollen eyelid that was no longer swollen less than 24 hours later. We have woke her up for the last two nights every two hours.. should we worry still? I hear internal bleeding can show up as late as 3 days? is that true? should we still be waking her up? should we worry?
