Question on day being missed due to LO being sick

UnderAtree

Last week DS was sick and I told STBXH that he was sick and I didn't want him taking him out into the cold and rain. I even offered for him to stay the day at my house so he didn't miss his time. Well he got upset, started a fight then stormed out the door. On Friday I got a call from my lawyer, apparently he went to his lawyer and told him that I am not letting him take him on his days and that I never answer his phone calls.

Other then one important doctors appointment this is the only other time he has missed a day. 

So today he told me that his lawyer said that since I made him miss a day I have to make it up to him. Now is this true? It says no where in a court order that I have to make up days if Ryan is sick or he I have to take him to the ER or an emergency appointment.
