Wa'alaykumsalaam Wa Rahmatullah Wa Barakaatouh.
First and foremost, your du'a as a parent is very important.
Secondly, as a two year old baby, i think it's quite early BUT it's always good to have them getting used to listening to the Quran - avoiding all kind of clips that are filled up with music etc ...
If they can repeat, allow them to repeat the Surah Al Faatihah or the words of Tawheed etc...
As a two year old kid, these are the things that we may start up with in shaa Allah - as they grow up when they can spell and memorize, then we may to the next level of Memorizing the suwars etc....
Allah knows best
