Hello, my son is 3 years old and just blabbers. He tries to speak but the words don't come out. Impedance and bera is normal. When he needs something he takes our hand and point out. Eye contact is present but when called by his name he will turn sometimes and sometimes ignores. He operates YouTube videos and knows how to change videos and also does skip adds when it reflects. Not sure what we need to do go get him speak. Is it speech delay?
