Nat will falls asleep when she is abt finishing her milk but sometime juz when she abt to fall asleep, she will wake up & cry then only giving her her milk will stop her from crying. She will drink a yi si then suddenly off to lala land.
so i think she got 'addicted' to the milk coz i tried water, she will drink but after awhile she will cry again when she realise it's not milk nia</font>
