just a little concerned really, i have noticed my 7 month old baby doesnt babble at all. he squeels, laughs and makes some other noises but nothing like bababa/dadada etc am i right to be concerned? he is quite advanced physically has been sitting up from 5 months, crawling, pulling himself up etc and he does react to us so definatly no problems hearing. he is a very irritable baby tho and needs constant attention or will screach really loudly so not sure is related or not??? just a little worried so would like some advice
