Just been at BF's house for tea. Another family were there and DS1 age 4 and another visiting 4 yr old were messing around and being v annoying. Sudden ruckus and DS1 was crying a lot. He told us that BF's DH hit him because he was being annoying. Mum of other child just phoned and confirmed this. DH mentioned htat DS had said this in front of BF's DH but he did not respond but was clearly v wound up. DO I say anything? DS1 rather wary of him now. BF would be horrified. Think it is a one off but not sure how confident I feel with her DH now and also feel a bit pissed off that DS1 has been made to look as if he was the one being unreasonable.
