THAT is NOT a sound you want to hear. It means your child just fell down the stairs probably taking about 20 years off your life! Jennifer fell down the stairs today....and bonked her head. I seriously think the baby gate at the bottom saved her from further injury. She acts like nothing ever happened......now that we are several hours out from the fall....there is not a mark on her. I don't know if she will have bruises appear later or not........I do when I get hurt.....my bruises don't show up right away. IN any case...she appears to be fine. I guess kids bounce well. It scared me so badly I was literally shaking on the inside. Thank God He gives His angels charge over us. Because but for the grace of God this could be a very different post...........so I praise Jesus.....my baby....is okay and not seriously injured or worse.
