hifdh with toddlers

assalamualaikum wa rehmatullahi wa barakatuhu,

From a long time, I am looking to start hifdh of Quran  with my 3year old son, but i couldnt find any source for how to start it with the toddler. As i was just thinking about it,suddenly an idea came in my mind of repetition. my son memorizes a lot of things from repetition and the brain of toddlers are like sponges as much you put as much they absorb.
 So i started a bedtime routine ( bcoz it is impossible for me to make him sit and start memorizing) so when we get into bed, I start tilawat and he joins me with it. currently my son is on surah albaqarah verse 5,and already done surah al fatiha, ayatulqursi, everyday duas and some short hadiths. Hope it will help you, at first if your child is not reciting with you, dont ask him over and over again  just keep reciting and inshAllah he will join you in few days but be consistent inshaAllah.

wasalam
