Sleeping

Julia • Kiwi girl, Kindergarten Teacher and Aunty to one beautiful nephew. Expecting our first little one January 2015
Can anyone tell me is it normal for a 7week old to suddenly stop sleeping during the day?
Around a week and a half ago my baby just stopped sleeping in her bed during the day only wants to sleep in people's arms,, but goes down fine at night (for now) 
I have tried everything, swaddle dark room different bed, pram, hammock .. You name it.
Is this an age thing?? Has/is anyone else having the same problem ? 
I'm super overwhelmed, I feel stressed about it
