She's never had any problem with her hearing that I'm aware of, her new teacher found she was slow to repond to her name been called. Plus felt she wasn't listen in assembly but has good listen skills in the classroom.
I brushed it it off with she never had an problem with her hearing but is a bit of a daydreamer. DD told me she really like assembly and sometimes doesn't hear things but normal because someone is whispering to her or near her (she's is easily distracted).
