passing guest,
1) since u are also direct feeding bb... of cos when u pump wun get so much milk lah... my advice is dun be so fixed on freezing ur milk now... maybe just freeze 150~200ml per day will be enuff (for the occassional day when u need an extra 1 feed)... cos when u return to work, u will still be expressing + freezing mah... if u freeze too much now, u will end up throwing away a lot of "old" milk hor...
2) it is not necessary to experience let-downs... let-downs does not equal more milk... try not to look at the bottle/pump when expressing... read a book/watch tv... if u keep looking down at the bottle, ur brain will subconsciously make u tense "why so little... aww..." then of cos less milk lah...
3) quantity also depends on how often u express to empty brs... are u diligently expressing every 3~4hrly or adhoc? try to get ur brs used to a fixed schedule (pref one which u can stick to aft u return to work)... then ur brs will adjust to know "when" to produce the milk...
4) There's no best time to pump... milk production is most between 1am~5am cos u are resting (sleeping)... but the milk produced are "thinner" and not as "thick" as those in the afternoon... see
What is Hindmilk/Foremilk and Letdown
You can try:
1. tandem pumping (which might irritate ur bb)...
2. pump after each feed if brs still feel got milk...
3. pump before each feed then let bb suck brs as empty as possible... cos a breast pump does not empty brs as well as bb suckle... BUT u may risk bb got not enuff to drink and scream lah...
(always remember: emptied brs will encourage milk production)
5) you can use sterilising tablets or if u dun like the idea, just use hot water to soak after wash (which is what I do since bb was 2.5mths)... dun worry, as long as u wash and rinse clean, bb wun need 100% sterilised stuff...
