I've always tried to engage Swe-cha in conversation and we're getting some progress lately. Katuwa because he used to just ignore me when I ask follow up questions but these days, he really makes an effort.
Swe-cha: Potato Sticks please mom.
Me: Why do you want the potato sticks ?
Swe-cha: I need eat!
Swe-cha: Florida, Seaworld
Me: What will you do in seaworld ?
Swe-cha: the shamu ride
Me: What will you do in the shamu ride ?
Swe-cha: do you want to scream ? ahhhhhh! (and raises his arms the way people do on roller coasters)
Swe-cha: Coke, Mom
Me: (I pretend to misunderstand) Okay, what do you want Mommy to cook ? Do you want egg ?
Me: Yes, I'll cook for you, what do you want to eat ?
Swe-cha: I drink the Coke, Mom.
Me: How about you just drink milk ?
