My 20mth old daughter often wakes us (& her 4mth old sister!) through the night by "crying/whimpering" in her sleep. She does not often wake herself but we don't know how to stop this crying. On occasion she has woken herself but often drops back to sleep quite quickly. Any idea what this crying/whimpering is and how we can stop it?
