The only time he every had him on his birthday was when he asked once to have him on New Year’s Eve and said he would bring him back in the morning. I told him to bring him back before 3 when his party started. He brought him home an hour late to his own party and was fighting me that if I kept bothering him he would bring him home even later. I was in labor for 2 days before having a c-section for him to be born and his father wanted nothing to do with him for 4 years so yeah it’s totally fair to share his birthday. 🙄
