Ds is six weeks and mix fed. He gets v hungry from about 6pm and has loads between then and about 11pm - about 250 ml formula in total and lots of breast in between.
Then at night he has breast only usually waking about 2am for it and sometimes 6ish for a little suck too. Then he's not really hungry until about 1pm. He'll take a 90ml bottle if offered am but doesn't clamour for it if not. In fact he doesn't really that eat much between 6am-4pm. Maybe he thinks it's nighttime.
I've tried to switch the balance and offer less in the evening and offer breast more frequently etc but he goes crazy in the evening without it.
