He has a proper meal before bed + his usual milk. But still he wakes up basically every 2-3 hours every night.
During the night he drinks about 120-160 ml of milk everytime he wakes up.
So to me it looks like he is constantly hungry.
He is a very active baby. Walking and busy all day long.
Maybe this is just normal to him. His brother slept through the night from 7 month old.
