*Long Post* I need advice. I just got home from the hospital after having emergency surgery. I can't do much with my son or anything because of it. Well we went over my fiancés parents house. Now we have had problems with them in the past and that is a known thing between me and my fiancé. Now I told everyone I was going to take a nap because I'm tired from the medicine I needed to take and they were all 3 watching my son. I wake up two hours later and my son is gone to a park with his two grandparents. Now I don't trust his two grandparents because of how they've treated me in the past and I am just now warming up to them. Well my fiancé just thought it would be okay for them to just take him to the park without the proper sunscreen to go swing. He knew I was going to wake up mad but let them take him anyone and didn't even wait for me to wake up or anything to talk to me about them taking him to the park. Am in the wrong because I am upset I wake up after taking my medicine I need because I just had surgery and my son is out with people I don't exactly trust at a park where I have no clue where he is and his dad knew how I felt and I would of wanted him to talk to me first?
