It’s been more than four years since Tom Cruise has seen his youngest child, daughter Suri Cruise. And as you can imagine, he’s missed a lot in her young life, considering four years can bring about a lot of change for anyone, but it’s especially monumental when the person in question is only 11 years old.

To this day, the 55-year-old won’t say why he hasn’t seen his daughter in almost half a decade, but many speculate it’s because she and her mother, Katie Holmes, left the Church of Scientology and therefore both were labeled “suppressive people.” In the church, a “suppressive person” — also labeled an “SP” — is someone who left the church, and is considered a threat to the religion as they get in the way of “spiritual progress.”

Though there have long been whispers of a father/daughter reunion — in September, an insider exclusively told In Touch that Katie was reaching out to her former husband in hopes of reconnecting her daughter with her father — no such reunion has happened.

But that doesn’t mean that lots of other things haven’t happened in Suri’s life in the past four years. Check out the pics below to see every moment — both monumental and minor — that Tom has missed in his little girl’s life.
