Baby sleep

Katie
So it seems as though baby sleeps better at night when he's awake more during the day. Everything I read says to not keep him up during the day and to let him sleep. He went through a growth spurt recently and was up all day feeding but then slept two 4hr stretches at night. Now he's back to eating normally and daytime napping but wakes up every 2hrs at night. I've tried swaddling him but he just sits there fighting the swaddle and crying. But then he startles himself awake. I know at this point they are changing often and there isn't much room for a routine but there is so much differing info on newborn sleep. You can't help but feel like your doing it wrong!
