I had a similiar problem with my son when he first started school. I remember he was not even 2 yet and i put him in a child developmental school. I remember his teacher calling me one day and asking us what we speak to him at home, because he was having a hard time understanding the teachers. Then she proceeded to tell me that she thinks that he may need a speech therapist. I was so worried, he was my first kid and he had a little sister just 1 year younger then him. Well as it turned out he was just fine, all children are different, they talk when thier ready and they walk when thier ready, dont push them. My son took along time to talk, hes now 4 1/2 and he speaks better then some 5 and 6 year olds i know. I also want to share this with you, children usually pick up a second language before the age of 3, they are like sponges right now. I say teach your daughter as many languages as you possibly can, its a blessing, trust me you will not regret it. My husband speaks 6, and he is trying to teach our kids at least 3. Just to add, my daughter was saying her first words at about 10 months, she knew her alphabet before age 2 and i have a 1 1/2 year old who believe it or not, just started walking, i thought he never would. My advice, dont sweat it, embrace it, your daughter would be blessed to speak more then 1 language.
