Parental term that is phonetically more difficult to say than "dada"

MAMA

This common maternal title often comes after "dada" in a baby's first words.

This clue plays on the idea that babies often say "dada" before "mama" because the "m" sound is harder to pronounce than the "d" sound. The answer "mama" fits as a common parental term that’s phonetically more challenging for infants. It’s a simple but clever way to highlight a well-known developmental milestone.
