Sudden bedtime screaming
Your baby who used to go down without protest now screams when you walk out of the room. This is separation anxiety — a completely normal and healthy developmental milestone. Your baby's brain has developed object permanence: they know you exist even when they can't see you, and your departure now carries emotional weight. Keep your goodbye ritual short and predictable (a kiss, a phrase like 'I love you, goodnight,' and walk out). Sneaking out actually makes anxiety worse because they can't trust that you'll be there when they look for you.
