My six-year-old daughter and I were changing the diaper of my sister’s newborn baby when my daughter pointed at her little cousin and said, “Mom, what’s that?”

Since that day, I’ve been visiting her almost every day. I take the baby with me so she can sleep, take a walk, or simply feel human again — not just a constantly anxious, exhausted mother. Sometimes I think back to that day and realize how close she was to the edge.

And how important it is to have someone nearby — someone who offers a shoulder at just the right moment.
