I have the same problem with you.
my child was already 9 years old when she came here. she has more difficulties in learning the second language. maybe it is because she has to learn not only listening, speaking but also reading at the same time.
OMG~~

it's no big deal!they'll learn just as quick as me~~
maybe about 3 yrs or less~~it's normal~~
