Almost 4 yr old not potty trained

Amber

My son will be 4 in the beginning of may. He has showed no interest in potty training what so ever. We’ve tried a time or two but I didn’t want to force it on him too hard. He just kept peeing on himself and playing in it🤦🏼‍♀️ idk what to do. Both my girls were potty trained by their 3rd birthday.
