There were no tears. No one actually knew how bad the impact was until she stood up, turned to look at the door stopper and exclaimed "Huhhhhh!!!!" There lying on the floor was the door stopper, and a metal piece with screws which was supposed to hold the door stopper to the wall (see photo below). The entire piece had been brought down on impact!!! Di had to hammer the entire metal piece back on the wall after that, before the door stopper can be screwed on to it again.

While Di was busy playing the handyman, my heart raced as I checked for wounds/bruises on Xuan. She had an angry red, bruised area where her left kidney is located. No obvious cuts because the gathers of her Mamypoko pants cushioned her soft skin. My heart felt like it had been sliced into pieces, nonetheless. I prayed that night, asking for God's healing (should there be internal injuries which the naked eyes can't see) and thanking Him for watching over the munchkins when I wasn't. She could have been hit on her head, can you imagine that???!!!
Xuan went to sleep smiling that night. The entire incident didn't bothered her at all while Di and I had to discuss action plans for the following day should bruises or signs of discomfort surface. It's been 3 days and we really thank God for delivering His promise to protect the girls while we committed them into His hand. Xuan woke up on Sunday with no bruises, no signs of discomfort and no recollection of the ordeal. She's a miracle child indeed.
Note
We managed to work out an interim solution. That is to wrap the door stopper with a foam pad (see picture below). If you have any better suggestions, please share. Thanks!
