I think it would be a good idea to make an appointment with a developmental pediatrician, or even an Occupational Therapist for an assessment.
best wishes.
He did clap and wave from 6 or 7 mos until about 13 mos. He never pointed. So, not only delayed but some regression. On our 18 mos check up our Pediatrician didn't seemed concerned, so we decided on early intervention. I guess the real question is do we bypass the intervention and make an appointment with a developemental pediatrician?
delayed, are you saying he used to clap, wave and point but he no longer will?
