"The other day my daughter Chicago fell out of her high chair, cut her whole face, stitches, had to figure it all out," Kim revealed of the toddler, who recently celebrated her second birthday. "Stuff happens and you just gotta roll with it."
So how is Chi Chi doing?
"She's OK, yes. Big scar on her cheek, but she's OK," Kim told the crowd.
Kim previously told ET, "I feel like having four is so much more zen. I feel really calm and zen. They all love each other. The baby really brought back, my two older kids would fight a little bit, and now since the baby's here, everyone gets along. Everyone loves each other."
