Hi,
I am a mother raising two kids, 4-year-old girl and 2-year-old boy.
They both started learning English last year but the output does not meet my expectation level.
My suggestion may not be usual.
I am providing a room and a separate bathroom to stay for free.
For return, I suggest you play or read books with my kids for about an hour everyday.
If anyone is interested in this, let me know.
FYI, I graduated from MBA at Carnegie Mellon University in 2007 and studied design at Parsons School of Design in New York in 2004. I also worked in Silicon Valley for many years before back to Korea. I am pretty familiar with foreign culture and so is my family.
Best,
Sun
