question: tonight my 21 month old son was playing and all of a sudden stopped and started crying so i went over and picked him up and he just stopped and put his head on my chest then wouldnt move or look at me it was like he couldnt hold his head up or concentrate and i noticed he had his tounge pressed tightly againt the roof of his mouth. this lasted a few minutes before i got him to drink some water then he just came back into it and started playing again and seemed fine. he did almost the same thing about a month ago and i didnt think too much of it because he was sick and tired but tonight i cant understand why this happened again, any ideas? i plan to call his pediatrician first thing in the morning but would like some insight as to why this happened?? - Tiffany
