Helping son speak, recommendations?

I have a wonderful little 1.5 year old boy. He's a total ham and loves being the center of attention. Smiles and waves and babbles non stop. Endless verbal diarrhea. His mother and I always try to speak clear sentences to him, simplified of course. We try to take his babble and give him words small enough to remember and relate to what hes doing.One of his favorite activites is reading. I would say out of an average day he probably is read to about 1-2 hours. He just seems to have no interest in trying real words. When he was about a year he struggled out the most adorable "hello" ive ever heard, but hasnt mever attempted that one since. and he will say "mumma, dada, and all gone". When you speak to him he will stop and listen and consider what youre saying, then just wander off babbling.Im not terribly concerned as our pediatrician has said that boys tend to be later speakers than girls, I just didnt know if anyone had any tips or recommendations to help him verbally progress. via /r/Parenting http://ift.tt/2EozSZG
