Hello, my grandson will be 3 on Oct 4th and is still talking gibberish where no one can understand him. He has been known to sound out the very rare word, but even then it isn't clear, for example "go" would be gwoooooooo or "engarde" would be ngaaaa. These soundings are not used often and are not becoming clearer. There is also very few of them where it seems he is trying to repeat what we are saying. I would estimate his actual library of words to where we can somewhat understand him to be no more than 8-10 words. 2 days ago when we were leaving somewhere, for the first time he actually said "bye" where we all understood him, but has not repeated it since as clear. He will carry on a full conversation with himself, or talk to a family member quite a bit, even though we cannot understand him. My son in law sees this as no problem what so ever and that my grandson should be allowed to learn at his own pace, no matter what that is. My daughter has said she would consider getting him checked if he isn't "talking" by his 3rd Birthday. I know it isn't my place but I am very concerned and would at least appreciate knowing if my concerns are warranted and if so, what should be their first step in getting my grandson the help he needs? Also, is this common, or a possible sign of something inheritant? My youngest son has severe Cerebral Palsy, and also my childrens father has another son with minor CP and other disabilities. Please, any advice would be so helpful and welcome. Thank you for your time and look forward to hearing from you.
