What makes the difference?

Nap time at 2.00pm (at babysitter's)
1. Babysitter puts Shanna tummy-down on the mattress
2. Goes out of the room to get something
3. Comes back in to find Shanna asleep

Nap time at 7.00pm (at home)
1. Mummy soothes Shanna, puts her down on the mattress and tells her it is time for her nap.
2. Turns Shanna over to her tummy.
3. Mummy starts to pat Shanna.
4. Shanna starts to cry (very loudly)
5. Continues to cry (face all red, tears are coming out)
6. In her attempts to get up, rolls over to her back
7. Mummy tells her 'go to sleep, Shanna', turns her back on her tummy
8. Shanna doesn't stop crying
9. Rolls over to her back again
10. Repeat 7-9 another time
11. Finally Shanna's hands move to her sides, cries less
12. Cries subsides
13. Falls alseep finally!

Bedtime at 9.30pm
1. Mummy puts Shanna down on the cot on her tummy
2. Mummy starts patting Shanna
3. Shanna looks around, puts her face down on the bed. No crying.
4. 5 minutes later, Mummy stops patting
5. Shanna's eyes are still open, but getting into sleep mode
6. Mummy leaves the room
7. Returns to the room 10 minutes later, Shanna is asleep

Recently, Shanna has been making a lot of fuss during her day/evening nap times at home (no fuss at babysitter's, and no fuss at bedtime!?). We tried various sleeping locations (in her cot, on our bed, on the mattress in the living room), same results. We suspect she has too much fun at home and doesn't want to nap. Wish we can look into her mind and find out what she is thinking!
