I just thought I would give you another opinion...not saying mine is right, just sayin' I just went through this and this is what I did

Not sure exactly how old your LO is, but right about 12mo (a little before and a little after) DD started having a 530nf. She is EBF all from breast (refused all bottles and was not good with sippy) and she was on a good amount of solids (BLW).
She was still doing 4 day feeds when she started the 5am thing, but her 2 mid day feeds were very quick and more of a habit than her really needing food. SO, I cut one of the mid day feeds to make the other one larger. So then she was having 3 big day feeds instead of 2 big 2small. I know the 5am feed was bc she was just plain hungry. She was sleeping 12-13hr nights as she went to 1nap early (spirited) and could not make it all night without that feed. (she is small, in the <3%).
The GS ended and now at 13mo and 1day, she has dropped down to 2 BF by herself. I offer and she says NO or signs to nurse when she wants to nurse. She actually dropped the first morning feed and is now BFing before her nap and before bed.
So just another experience in case you think it fits your situation
