What does canon have to do with any of this?
It's there because George Lucas says it's there. Enough said.
You feel you have to see every day of the ten years between Obi-Wan and Anakin to be convinced? To see how he evolved from a bright, bold kid into a moody young man? (lots of kids become moody once they hit the teenage years.)
If you stop to think about the characters, you can find your answers without having a filmmaker just blunty tell you what is happening. Anakin was made an apprentice at an unacceptably old age, but was made an exception because of his huge potential. He already had a value system and family attachments - Jedi are found at a much earlier age, so attachments can't be formed. Anakin still couldn't let go of his previous life, and wrestled with the Jedi principle of solitude, which forbids marriage. This is going on under the surface for him by the time we see him again in AOTC. It's referred to in indirect ways through the film, and Obi-Wan is concerned Anakin doesn't have the emotional maturity to handle his gifts. You can discover all this if you reason it out, from what was seen before and what Anakin says now.
George Lucas trusts his audience to figure things out, without him having to explain every single detail.
