What do I do? Every time my brother walks out of the room she yells DAAADAAAA after him. Her dad hasn't seen her much lately and I'm a little worried about her getting confused. My brother is staying with us for a few weeks so she is around him all the time. It was funny the first few times she did it, but I don't think its funny anymore. Is she going to be messed up from this? I always correct her and say uncle Matt, and repeat it a few times for good measure. What else can I do?
