im not gonna tell you not to worry, becuse quite frankly you have every right to
but i watch a 2 year old (he turned 2 in faburary) and he use to not talk, he would point to something and grunt, then the grunt turned into him saying yeah, that was it, it was because his sister and old babysitter would talk for him and allow him whatever he wanted just by pointing
his doc got conserned and sent him for a hearing test, which came back perfect (as we all knew it would) and then he started comming over to my house and i watched him and his sister during the day (still do) and with his mum and me working together he now says a lot of words (mommy, mama, dada, baby, ball,ok, yes, ne, please, more, eat, pee, potty, poo, hair, eye, nose, teeth, knee, arm, etc) we dont let anyone talk for him and we pretend not to know what he wants when he just points, he has to say something befor ehe gets anything
his lack of words has really made potty training difficult, but were working on all this
i know no two kids are the same, but i hope my experiance with this kid can at least give you a little hope, im sure he is very very smart boy, he may just be being stubborn like alex (the boy i was talking about) is (and yes, it is just stubbornness now, he will say a word without meaning to and then pretend not to be able to say it again until you practically force him to lol)
