My 9 week old baby is sleeping quite well during the night, she will go to bed about 10.30 abd wake at 2.30 for a feed and then sleep another 4 hours.

However during the day she will not sleep, she will only have a few 15-20 minute cat naps. I have tried everything:
- Darken Room
- Wrap her like I wrap her at night
- Soft Music
- Resettle her after she wakes after 20 minutes (some times she will go back for another 15 minutes but usually not)
- etc etc

I am a big believer in not rocking her to sleep and she does fall asleep herself, so getting her to sleep is not usually the issue.
I want her to sleep in her own bed during the day and dont want to resort to having her sleep or fall asleep in rockers etc during the day.

Any advice as I am at my witts end as she gets so overtired that she becomes a mess at about 4pm every night and doesnt eat well and fights sleep cause she is so tired. It will then usually take me until 10.30-12.30 at night to get her down for the night.

Need some advice????
