What is Echolalia?

In a normal developing toddler, echolalia is salient (conspicuous), climaxing at around 30 months of age. If you don’t know whether your child’s echolalia is
normal, keep a list of what he/she repeats. See if it changes over time.
If it doesn’t, & if new vocabulary or responses are lacking, then
consult a professional. Especially if you have an older toddler
around 3 years of age.
