Hi and Welcome zuzu, My DD who is also 11 loves using the TM, she is quiet confident and I can trust that she does the right thing. My to oldest DS's have not gone near the TM as yet as they are not comfortable with it and leave all the cooking up to me. I'm sure your DD will be doing alot of cooking when you give her the chance. Hope you don't have to wait to long for your TM to arrive.
