As a practicing Speech-Language Pathologist for 6 years now, I have seen the importance of pre-linguistic skills. The primary is eye contact but the next for infants/toddlers is VOCAL PLAY. Some will challenge me to say that motor imitation is second however I find many 6 weeks-12 week old infants being to coo back and forth in response to their caregiver as well as in response to pauses much before they start to imitate clapping, waving, baby sign language.
You may be sitting there saying, DUH! However, we need to teach parents how to implement vocal play before we address first words or expressive language delay. We have to create the foundation for imitation to build language development.
I by no means desire to provide handouts that eliminate the need for structured therapy, however I do see the amount of children with slow progress due to lack of parent involvement. IF we can help SLP's improve the education provided to parents for home-programming and carryover, then we help the child on the path to success. My end goal is to get my kiddos OUT OF THERAPY!
