Leaving off beginning sounds???

[Guest guest]

My DS is 2 years old with moderate hypotonia. When reading the " typical "

milestones it states that children with leave off the ending sound and sometimes

the middle, BUT produces the beginning. My son does the EXACT opposite by

saying the ending, not the beginning (even when able to say the beginning

sound). For example, the word " snack " , his response, " -ack " , even though he can

say the /s/ sound in isolation and the /ack/ in isolation, when asked to put

them together he only produces the /ack/ sound.

How anyone else experience this?

On a side note, he is not able to produce the /b/ and /p/ sounds, in isolation

or with words. I " believe " his tongue protrudes causing him not to be able to

say these sounds.

Please HELP!!!
