Speech and language development milestones relate to receptive
language (the ability to understand words and sounds) and expressive language
(the ability to use speech and gestures to communicate meaning).
Receptive language skills are the first communication skills learned.
Expressive language also begins soon after birth. Speech progresses from
isolated sounds to possibly making a simple word or two (like "mama") by the
end of the first year.
