Baby Sleeping

Julia • Kiwi girl, Kindergarten Teacher and Aunty to one beautiful nephew. Expecting our first little one January 2015
Just wanting quick reassurance /help if it's normal for my 3 week old baby to only be sleeping a max of 2.5 hours at a time durring the night. I'm waking her durring the day for feeds, but at night I can't get her to sleep for long. Sleep deprivation is getting to me haha :(
