I sent you a contact list by email. You can refer to the list cos I made the matching with our BK ID, FB ID, Mommy's Name, Baby's Name & email address.
I pump twice and direct feed my boy twice too. But, my volume drop gradually and now don't have any spare milk can be reserved.
Since my boy nearly 13m, I don't think it's a problem until I can't collect sufficient volume by 2 pumps at office for his tea-time meal at home.
As you girl only 7m, she may not able to eat too much solid food and may still quite relay on milk. Like my boy's case, congee fully replace one milk meal at 7.5m and two at 9m. My suggestion is if you really think your health problem is due to breastfeeding, you can reduce your milk volume up to your girl's need level. Don't need to save sapre milk. Or, you may consult doctor/chinese doctor to see whether you can eat anything to make you healther.
