Okay, so sometimes when a mommy is going to have a baby, the baby doesn't grow in her tummy the way it's supposed to. This can make it so the baby can't live outside the mommy's tummy, and that's called a miscarriage. It's very sad when this happens because the mommy and daddy were excited to meet their baby, but they won't get to.
When a baby is born but can't stay with us for very long, that's called infant loss. It's also very sad because the mommy and daddy were excited to take care of their baby, but they won't get to. Sometimes this happens because the baby's body wasn't strong enough, or there was something wrong that the doctors couldn't fix.
When someone loses a baby through miscarriage or infant loss, they might feel sad and alone. That's why some people make or buy a special book where they can write down their feelings and memories about their baby. This book helps them remember their baby and honor their memory. They might also put pictures and special things in the book to make it even more special.
It's okay to feel sad and to miss your baby, but it's also okay to remember them and keep them close to your heart.
