How has the speech learning process been for your LOs?

DS is 12.5 months says a few words here and there, mainly "umma" korean for mom.

I'm not too concerned yet, but wanted to set my expectations for where he should be in the coming months since I hear that speech may be delayed in LOs who are exposed to two languages early on.

I speak both Korean/english, DH speaks english, my mom who is his primary caretaker when Im at work speaks to him in Korean.

He understands both languages and responds to both with action, but curious as far as verbal development since that is his huge milestone in the upcoming months.
