In my un-informed opinion the difference between your daughter learning a new language and you is that your mind is full of thoughts. &quot;Gotta pay those bills tonight&quot;, &quot;gotta plan that vacation&quot;, &quot;Gotta solve that problem at work&quot;, &quot;gotta stop and get groceries&quot;....<p>At least that&#x27;s my experience. My mind gets more and more busy with racing thoughts the older I get. It&#x27;s hard to put that aside because the older we are the more responsibilities we generally have (and or worries)<p>That&#x27;s the long way of saying age has nothing to do with your daughter doing better at language. Rather it&#x27;s that her mind has far less distractions.<p>ps: yes I know there is research on this topic but I have not personally found it compelling
