Hey ladies, has anyone elses lo gone through a three week growth spurt? For the past two days Brenna has been close to inconsoleable. She is hungry all the time. We are totally on formula (my supply just dwindled) We are feeding her 3ozs every 3 hours and it still is not enough. I have given her 4oz today to see if that would help. But it still seems to no avail. She is so fussy and cranky. She will not sleep b/c she is so fussy. I know it is a vicious cycle. I really have no idea what to do for her. She is crying all the time! Any advice you have would be much appreciated!
