Awwwwwwww Linda, don't feel like an idiot you did the right thing. If she's not doing her job properly then she needs to be told. The only reason you even did anything is obviously because they've had lots of complaints about her and they asked you to make a formal complaint, in doing that they are probably looking to give her the sack so she won't be there to give you any flack (well hopefully not).

But you totally did the right thing for Emma and all of the other children that are in her care.
