Thank you so much..

My daughter said " I am saved" in my mother tongue.

JUNHEE LEE" I am saved" in my mother tongue.

Now you know that that doesn't translate meaningfully into English.

JUNHEE LEEI was holding pee.

In the UK, people would say I was holding in a wee http://dictionary.cambridge.org/dictionary/british/wee or, I needed to wee but was holding it in. Small children often say wee-wee, while everyone else usually says wee.
