YES! my trip made a huge difference. She was speaking 50/50 after only a week! now, couple months later, we are back to 100% english :-( and I'm fining myself speaking to her in english more and more because I think she might not understand polish... this is VERY hard and if someone tells me otherwise they will be lying. I'm trying to stick to it thou and I will TRY to make her repond in the proper language (English for daddy and Polish for mommy) especially now that she understands teh difference. On a better note, when we speak with my parents via Skype, she speaks Polish to my parents, but very limited.
