My wife and I speak to our daughter (13 months old) in Hebrew and in English, respectively; we're careful that each of us speak to her consistently in our own language all the time.
She's on the verge of her first words, and I instinctively want to encourage and strengthen her when it comes to "words" she recognizes. The issue is that some of these phrases are in Hebrew - and I'm not sure I should be repeating Hebrew words to her, when I'm trying to stick to English. For example, she recognizes light and light fixtures, and says "Oh!" - very close to אור, "Or", Hebrew for "light" - and I feel very silly saying "Yes! 'Oh'! Light!". That seems unnecessarily confusing.
Under these circumstances, how can reinforce her attempts at first words while keeping up the bilingual distinction?
