I have started to worry about my supply. I BF morning and night and express 4 times a day (usually) on top of this as I am back at work full time. My DD is 4.5 months old. DH told me that DD is drinking a little more lately and he's been dipping into my freezer stash so I have been trying to express 20 mls more/session. I usually get:

1 - 200mls
2 - 150mls
3 - 150mls
4 - 100mls

DH thinks DD is drinking about 700mls/day now so I figured I would try and get 20 mls more per express and it would be all good. I've noticed her morning and night BF's are getting quicker but she is still fully emptying both breasts so it makes sense to me she is increasing the milk she wants. But today I got this:

1 - 220mls
2 - 80mls
3 - 80mls
4 - 60mls

WTH? I actually expressed another couple of times other than the above and got 80mls both times because I need to milk for DD. I do have a really good freezer stash but I am so worried that my supply has dropped all of the sudden. I have googled lactogenic foods and will be drinking ginger beer all day tomorrow But other than that, does anyone have any idea why this would happen? Anyone experienced this before? This has never happened to me before and recently I've been feeling like I've got a bit more milk than needed again rather than not enough.

Feeling a bit worried about it all.
