I completely agree about the bruises. My son's legs especially are covered in them - what can I say, he's kind of a klutz...
However, the bruises that his school has been documenting have not been "typical" and they always appear after weekends with mom. The school documents what they see fit.
As for my son telling me what he thinks I want to hear: my son first told one of his teachers. Teacher saw him sitting by himself on the playground crying and asked him about it. She was the first person he told. I talked to him about it once, and then we've let the therapist probe this issue. I ask him about his weekend in general and he again this week brought up that the BF hit him again.
I was contacted by the PO on Friday. Seems he issued an arrest warrant for the BF, who said he would cooperate. The PO said that we could ask for a no contact order if the BF is released pending further investigation (something like that).
