My DS went through the exact same thing at about 3.5 -- I posted about it here. He would talk about wanting to be a girl, and get teary-eyed about it, and ask how he could turn into a girl. It broke my heart to see him to be seeming to struggle so much with his identity.
The mamas who responded to my thread mostly told me to give it time to sort itself out, and until I read your thread I didn't even realize that it hasn't been an issue for several months! He hasn't brought it up at all.
So, I don't know -- it may be something he'll come back to when he's older, or it may not. But for now, it looks like it was just a phase. I gave him some pretty clear messages that I love and accept him just as he is, and will always love and accept him no matter what, so hopefully he'll feel comfortable coming to me if this is something he thinks about more as he grows up.
