How I pump breastmilk at work

My daughter will be turning 6 months in a week and I am really overjoyed to have been able to exclusively breastfeed her. For working moms like me, here is what I do to successfully provide milk for my baby.
First let me show you my kit:

Pouch for my electic pump, igloo insulated bag for my bottles and ice pack

For an 8 hr work here is what I need:
    Double electric pump (Spectra M1 from babymama.ph)
    Pump accessories stored in a lock and lock container
    2 bottles to be connected to my pump (I use avent bottles since the spectra bottles seems loose)
    3 breastmilk storage bottles (Looney tunes brand)
    5 Ice packs (The blue one lasts only around 4 hrs while the silver one around 6 hrs)
I decided to use a double electric pump so that I can be more efficient time wise. Instead of 15mins per breast I can be done in 15mins for both breast. I used to have a handsfree pumping bra but I dont use it anymore since I find it much of a hassle to put it on so I just hold both breast pumps using my left arm. Then my other hand is still free to do some stuff (Facebook, online shopping hihi)

Here is my pumping schedule:

06:45 Arrive in the office
07:00 1st Pump
           I store it in our clinic's ref together with 3 ice packs
10:00 2nd Pump
15:00 3rd Pump
**17:00 If I need to extend time in the office I would still pump. Otherwise I go home by 16:00 hihi

I don't clean my pump after each session. I just store it back in my insulated bag together with the avent bottles and leave atleast 2 ice packs. During my 2nd pumping time I just change ice packs from the ref. This remains cold throughout the day. As for my expressed milk I keep it in my looney tunes bottle and store it in the clinic's ref

Each session usually lasts around 15 to 20 minutes for me. And I normally get 4 to 5 oz. So everyday I am bringing home around 12 to 16 oz for my baby girl's consumption for the following day.

I think the key to sustaining breastfeeding for working moms is to pump regularly. Try to express milk every 3 to 4 hours to maintain your supply regardless of what technique you will use. Some moms has done it using hand expression which I have yet to try.
