My DD is six weeks old and is ff. She happily takes 4 to 5 oz per feed during the day, but for the last couple of nights she has taken 1oz and then started crying if I start to encourage her to take any more. This happens at her midnight feed and around 4am feed. Has anyone experienced this? The only thing I can think of is that her body might be taking less at night in order to gear up for sleeping through... Is this just wishful thinking? Any experiences?
