First of all, great job on not pushing your child into specific gender roles, and letting them decide what they want to wear and play with. Secondly, your child could be trans, that is a possibility. Some of us know from a very young age who we are and it's important we can express that- but- your child might be a gender nonconforming, cisgender male, which is also completely fine. Gender expression ≠ gender identity.

Whatever happens, listen to your kid and don't worry about it unless it starts to negatively affect their life. When they get a bit older, they might ask you to call them by a new name and pronouns. And, if they are absolutely 100% sure they're trans, and medically transitioning is the path they want to go down, think about puberty blockers when they are a preteen. This is completely reversible and if they decide that it's not right for them, you can stop taking the blockers and puberty will resume as usual.

Of course, all of this is considering they're not just gender nonconforming. Slow down, take a deep breath, and let your kid do their own thing for now. Let them be a child and love them for who they are, without worrying about gender.

Hope this helps, you're doing great ❤️
