"daddy hit me"

[Toregone]

I would leave it for now. My own son tells me that daddy hit him (daddy walked by and my son got brushed hubby passed him, same contact you'd have with someone in a mall lol) or tells daddy I hit him (touching the back of his head as he walks by me). Without repeat instances, or physical evidence of being hit (btw spanking should never be done hard enough to leave a mark.. that crosses the line) you really have no idea what happened. Dad could have simpily picked him up and placed him back in his bed, or yes he could have got a spanking. With kids, what they see as the truth is sometimes not what actually happened.

Document it, don't forget it, but I wouldn't act on it.
