My daughters 3 weeks old and i obviously have a low supply (considering i only pump about 2.5 oz in the am and it goes down to about a whopping oz in the evening and my daughter never seems satisfied or stays latched but does w a bottle) i need to stock up atleast 2 3oz bottles for tonight while my mothercin law watches her for a few hours later but everytime i pumo anything i have to give it to her pretty much right away and can never get ahead . What do you ladies do??? Thanks
