Hi I am a mum of 3lingual toddler ( 2 tomorrow) . He speaks little polish ,vietnamese and english . My husband and myself talk in polish but he and ds talk in vietnamese .My little one understands both languages at the moment but I am looking for some kind of guidance how to encourage him in the future to speak 3 of them ....We go 3 times a week to playgroup and he will start play-school in september to catch up on english ...I wonder what will happen when he starts to speaks english on a daily basis ??? We would really want to keep the languages.Any advise ??
