My friends pediatrician told her that they should know like 100 words or something crazy by 15 months and I was surprised by that, my son will be 15 months on the 19th and only knows mama dada water ball hi/hello nana(food) more oh no oh wow and uh oh and has said some other things but only once or twice. Now this is normal right? He does say yeah and point to what he wants and knows but can’t say it. I can’t imagine a baby his age knowing more then 100 words? My pediatrician never said anything like that! How many words do your little ones know?
