My 3 week old is constantly awake and it takes over an hour to put her back down....she's formula fed and getting 3(+) oz....anything less and she starts showing signs of hungry and will cry.

Both day and night she's up every hour! We are exhausted and can't get anything done as it takes a whole other hour to put her back down.

Why won't this kid sleep lol she's swaddle....she's been giving a pacifier .... her diapers are on track ....lots of pees and about 2-3 poops a day...she's changed often. Its been going on since birth!!
