The first time Michael's father tells Tara not to touch the clock, she has bangs on her forehead. However, when she turns round to stick her tongue out at Michael, her bangs are gone.
When Michael is dreaming, he opens the door to the room the cuckoo clock is in and begins to scream. However, his scream is heard before his mouth opens.
If Tara was born in 1988, she would be 7 years old in 1995. So if Michael was 6 years old, Tara should already at least be a year old.
