It's a baby.
What else should I say?
Watch out for dirty diapers.

Watch out for the Crying!
Shrieking Scream. Whenever the baby is injured it has a chance to charm all humanoids within 100ft of it with an intelligence save DC of 15 (except for the one who attacked it).

Charm. Every creature that has a line of sight of the baby has to succeed in a DC 18 Wisdom saving throw or be charmed. A charmed creature can't attack the Baby or target the Baby with harmful abilities or magical effects. Charmed creatures can spend an action to repeat the saving throw, ending the condition on a success.
