Latching

Sarah
My month old won't latch correctly, he just sucks on the nipple, once I correct it he reverts to just sucking on the nipple, after trying 10x I give up. He gets so angry and starts crying uncontrollably. He's so flipping strong and puts a huge fight which I end up losing!  Any suggestions? I don't think he's getting milk efficiently, he kept me up all night.  I  am trying to be patient but I am SO exhausted! Words of encouragement are also appreciated! I am having a hard day :/ TIA
