When do you start teaching your children about Islam? I mean basic things…like how to say “Assalamualaikum” or to recite “Bismillah-i-rahman-i-raheem” or the kalma?
and…hoW?
Re: when to start
my daughter is 6 months old masha allah ...when she wakes up in morning I say Asalam o alikum to her ....when i come home from work i do the same...when she sneeze i say alhamdolillah.....all of us at home do like this with her thats how she will learn basic things.
I think my mom will start teaching her basic things at the age of 2.5 or 3 years.
Re: when to start
Like diamond said, start using these duas regularly, always read Bismillah out loud before starting anything (eating etc)...read kalma etc....read dua for sleeping righ tbefore sleeping out loud...let the kids watch u read namaz...do wuzu...etc...slowly they will pick it up. My son knos kalma, bismillah etc...plus we teach him little bits at a time and he just memorizes it, and gentle reminders and positive reinforcement...it works sometimes...hehe io got a stubborn kid :)
u do it from the very begining... i did it from the day they (both sons) were born... both times as soon as the nurse gave them to me i greeted them with AsalaamOaliakum.... and after few hours i recited whatever Surahs i remember in their ears ...
they all learn at their own pace... my older one (will be three soon) recites ChaarOqul with me every night... he was very clear in his wordings from the very begining.... my other son (soon will be 2) is not very clear and still says toota phoota Khuda Hafiz
Re: when to start
I once heard a scholar say that starting to give your child an Islamic upbringing as soon as he/she is born is starting too late...their upbringing starts when you select your spouse, the person who will be their mother/father. Its part of the rights of the child that their parents select a good, righteous parent for them, who will raise them well
Besides that, I agree with that the other said. Start right from the start, even if the baby cant talk yet, at least they will grow familiar with everything if they see it as a constant in their life. When you are feeding them, always saying Bismillah..and then as they start to speak, encouraging them to say it with you..etc
i think its the right time for paapa/mama 516 to start teaching you that.

From the day they are born.
Re: when to start
Start right from the beginning - ull be surprised how fast kids pick up words. theres also various dvd's, youtube videos that you can show kids combined with barney/dora etc so that they can pick up Islamic words aswell.
Re: when to start
thinking of it now, we never really taught them to say "as salam wa alikum". They learned it them-self by observing us.
More important thing is to say or "do" things that you want them to learn. If parent do these thing more vocally, kids normally are smart enough to learn
Babies like to be held and read to. Just cuddle them up and read Quls, Surah etc.
Some of my friends have Qirat in the car.
My daughters used to say "cha ma lai kum" even before they were one.
Re: when to start
I think this is the kind of stuff that's really taught through use. I greet my daughter with "Assalamalaikum" every morning, etc. If they hear you use these words, then they learn them. Otherwise they'll know theoretically that's how they are used, but won't apply them unless others around them do.

True....I don't disagree with anything said here....
but sometimes things don't work out that way!

Re: when to start
^^agree!
Re: when to start
Before they're born. I read the Quran out loud, I always imagine them listening to it, and I follow recitation with duas for my hone-waala-little-one :)
And i agree with whats mentioned above, kids learn through observation.
