Any issue that impacts the best interest of the child will be relevant in a child custody trial. Without know more information being the entire situation, it is impossible to say whether this is a relevant factor to consider. Just because a 2-year old cries does not mean its because he's going with his dad. The 2-year old cannot explain why he is crying, and dad can simply say he's crying because he's not happy being with you. The best thing to do is consult a family law attorney to review your case and all the circumstanced surrounding custody to determine whether a modification petition is warranted. Good luck.
