Speech & Language Milestones in Young Children by Kathleen E.
Mahn* and Frances Page Glascoe, Ph.D.
Skills in speech (sound pronunciation) and language (listening,
understanding and using words) develop in an orderly way, although
the pace may differ from child to child. Below are general guidelines.
Most children will show these skills within six months of the
times listed.
Language Milestones
1 year: 1 word sentences (Stop!)
2 years: 2 word sentences (All gone!)
3 years: 3 to 5 word sentences (Me go potty.)
4 years: 4 to 7 word sentences (Let’s go to the store right
now!). Uses different parts of speech almost all the time.
How Many Words Does Your Child Use?
1 year: 1 to 10 words
1˝ years: 10 to 100 words
2 years: 100 to 250 words
2˝ years: 250 to 400 words
3 years: 450 to 900 words
4 years: More than 1500 words
Speech Sounds

(a, e, i, o, u)
4 years: k, g, t, d, n, ng, f
5 years: s, z, l, v, y, th, sh, wh, ch

How Well Can Others Understand Your Child?

3 years: 75% to 90% of the time
4 years: 90% of the time
Stuttering
Stuttering in the preschool years is normal.
Be sure to give your child plenty of time to say what he is
trying to say.
