I built a simple swing set for my toddler daughter. I just want to make sure that the beam can hold up for the two swings. I have two 6x6x12 post set 3 ft deep at 23 inch apart for a slide. Than I ran a 6x4x12 beam across the top of the two post. On each side of the post I have a swing. I will be adding sport 4x4 post connecting the 6x6 to the 6x4 on each side (drawn in red). Any support would be great. Used #2 pressure treated wood.
