I have suspicious my son might have been abused but I don't know if I'm imagining it.

One time, I was changing his diaper and I found 2 drops of blood, never happened again , and he seemed fined, then I don't know why in the morning he has a great fear of being change his diaper by anyone who is not me or his mother, but only in the morning, rest of the day he seems fine.I have only left him with my parents, my mother a couple of times had to go shopping and left him with my father, and my grandma and one house keeping woman, once i went and picked him up and the door of the room was locked, it was only my father and him sleeping inside, but I just thought why would anyone lock the door? its driving me crazy, i don't see anything abnormal about his behaviour or other signs of abuse, I don't leave him alone with anyone anymore, but I'm afraid to offend my father by asking him not to be alone with him. via /r/Parenting http://ift.tt/2gRN6Rs
