my baby is 13 months and he is very active, he can’t stay on one place so how do i teach him reading?
lol I have read some magazines that recommends parents to talk to their children even they’re still in their momma’s womb. 8) I can say it is a very good start of creating bonds with our children. 
Well for me, it’s not too late for our children to learn good deeds from us… be more patient with your teaching lessons and loving care for your babies… :yes:
I’d suggest after he’s been actively playing and is resting for a minute - in other words get the wiggles out first, the other idea is to do it while he is in his chair eating.
Find moments when he’s still and make the most of them! In the high chair, like LDSmom said, or right before naptime and bedtime, most kids will let you read a SHORT board book. Don’t expect too much; Dr Suess was way too long for my daughter at that age. If you’re doing Doman-style flashcards, stash them around the house and just show one at a time. Near the window, have “tree” and “bird” and show one when he’s looking out the window. Or try hanging labels on things and pointing them out to him when you’re in the area: “This says ‘fridge.’ I’m getting your milk out of the fridge.” If he likes it, you can also ask him to walk/crawl to whichever card. But again, don’t expect too much of an attention span. One flashcard is plenty at this age. And just be patient. In a few months, he’ll start being willing to read with you again and spend more time on one thing. At least, that’s how it worked with my daughter. Now at 18 months, we’ll spend lots of time sitting and reading, and five minutes building sentances with her flashcards. But around a year, it did seem like we could hardly concentrate at all.
I agree with Wolfwind. Children go through different phases and around 13 months they are often so much enjoying their new independence and ability to explore the world that it can be very difficult to encourage them to stay still for more than a few minutes. Remember to keep the lessons very short and don’t try to read a whole book. One or two flashcards may be all that you can show. If using physical flashcards you can show 2-3 at a time in between different activities, making it all fun and being very enthusiastic and positive so that he sees it as a fun game. Remember when flashing they only need to see the image for a very short time, so you don’t need to hold up the card and expect him to keep looking at it - just one glance is often enough to take in all that information using the right brain.
If you are using a computer based programme like LR then I also found that meal-times were the only really good time for my DD. At 3 she is still extremely active and difficult to pin down to one activity for very long, so we tend to do our strutured reading practice during breakfast. Again, I kept it very quick so there is still time for a family meal and general interaction and talking. With my son, I tend to give him a couple of finger food snacks like rice cakes whilst watching LR and LM, plus I do signs for all the words to increase the interactivity of the programmes. As your son gets used to learning and what you are asking from him, it will get easier! I think finding a routine that works for your family is the key - kids love to know what to expect and when. Good luck!
I have taken two children now through the 13 month phase and it differed only slightly between them - both by that age were walking and walking too priority. I use LR with my now 14 month old and just show it - she can sit on my lap and watch or wander the room if she likes - even if she is not looking I still just play it and move on the next day as she is hearing the words and will usually look up at some point in the presentation. Lately we have been having more success and she can actually watch nearly the entire presentation and show a lot of interest but it has been months of her wandering and playing with toys while it plays in the background.
I also use laminated flashcards in the bath - children are confined in the bath and these cards are like bath toys to them - they can dunk them in the water and stick them on the wall while I read them to them. The same cards sometimes get spread around the house where they can bring them to me and I read them to them.
Book reading time happens usually before bed time or nap time when the girls are a bit tired and more likely to sit still - I have still not been able to read a full book to my daughter as she likes to turn the pages haphazardly, but she is showing more interest in the pictures now. She of course also has a big sister who loves being read to which helps - I read to the younger first at night and then put her down to play with toys while I read to the older - she is hearing it too even if she doesn’t seem to be paying attention.
I have also stuck flashcards on the wall which I point out as they rush past.
Work with the inattention and don’t let it bother you. You do not need loads of time to teach them - just a quick glance at a single word a few times a day is fine - they are learning so very fast that being so active is fine too.
