infantile
Like a baby
Infantile describes behavior or characteristics associated with infants—undeveloped, immature, or inappropriately childish.
The clinical sense appears in medical contexts: infantile paralysis, infantile spasms.
More commonly, infantile criticizes adult behavior as embarrassingly immature: His infantile tantrums exhausted everyone.
The word carries more contempt than childish or immature.
