He's half Mexican so I thought it would be cute.

Good grief, he is 2 for Pete's sake! Transgender? Might as well assume he is gonna grow to be a construction worker for playing with blocks.

People tend to know what gender they are by the time they are three. Maybe he's just a little advanced. You can rag on tumblr and gender identity all you want, but trans people DO exist you know.

I've known I was transgender as far back as my memory goes. Parent's even told me I'd said things about being the opposite sex, but it was played off as "playing pretend". This was before I even came out. I told my dad very recently and he said he'd known from how I'd been when I was younger. It's very possible for a child to know they are transgender, but not EXACTLY know they are transgender. The concept is there, but the way to describe it is not. 24 years old btw, if you need that context.

2 is about the age that they start learning how to be potty trained. I knew some kids that were still in diapers at 3. It just depends on when they learn how to be fully potty trained. 2 is still quite normal to be in diapers ^-^

Not at all. Children are usually potty trained between the age of 2 and 3 but sometimes earlier, sometimes later. It depends when they are ready.
