A.P.
Oh geez, don't us mothers feel bad enough as it is.
When my son was just a few weeks old I was carrying him to his bassinet and I misjudged and whacked his head on the door frame...oops, he never woke up but I felt like the worst mother ever!
When he was 9 months old I thought a tension gate would work for the top of the stairs...nope, he fell down all 13 steps. A trip to the ER, and a cat scan later he was fine but I felt terrible, again.
Just over a year old he ate a screw, I was right there in the same room and in one swift movement he popped it in his mouth and swallowed before I could do anything. Everything came out fine in the end.
I've stepped back and knocked him over so many times not knowing he was standing directly behind me.
He's now almost 2 and loves me more than anything so he doesn't hold these little things against me :)
