Great question! I am just about to post one re: the night feeds :-)
My wee man feeds at 7am, 11am, 2.30pm, and 5pm ish (with a bottle at 7pm), BUT he used to take both sides for every feed, but now at 8 months is only taking one side (so I guess getting half?). He is also waking once or twice to feed so I wondered whether he was getting too much at night??? Dilemmas!
Nice to know I am not alone though
