I worry that....... how will she treat her new born baby????
It is because for all the 'normal' baby (under 1 years old) can't control for 'boo'. They will boo as they like everytime and everywhere...... i.e.
her baby may boo in front of her when she is eating, talking, watching TV, shopping, or taking the bus/MTR....... She will be very angry about her BB cannot control by itself and 'boo boo' in front of her!!!!
