Newborn help!! Funny sleeping patterns

So my little one who is 4.4week old is doing this weird 48hour sleep cycle, 24 hours of lots of sleeping followed by 24hours of mostly being awake. 
(She'll sleep all night and the next day (im waking for feedings two hourly durring the day) then awake two hourly the next night and practically awake all day.)
Is this normal? And how can I break the pattern of its not??
