The word 'Bettchen' is the diminutive form of 'das Bett' (bed). The ending '-chen' is attached to nouns to express that something is small or cute. Nouns ending in '-chen' are always neuter and take the article 'das'.

The kitten slept in its little bed.
The meaning depends on the context. If people are talking about a baby or a small child, it means a real, small child's bed. If an adult talks about their 'Bettchen' (little bed), it is an affectionate, colloquial term for their own bed.
Das Baby schläft friedlich in seinem Bettchen.
The baby is sleeping peacefully in its crib.
Using 'Bettchen' for an adult's bed is purely colloquial and emotional. It expresses a feeling of coziness, warmth, and looking forward to one's own bed.

'das Bettchen' is either a small bed for a baby or young child, or it sounds affectionate and diminutive. Learners may confuse the words because both have to do with sleeping.
