aaaarrrrgh, you say these are all signs you are not producing enough:
**Definitely not a growth spurt- all the signs are there that I'm not producing much milk-
Human beings can have appetite/growth spurts at any time, there is no age limit! Your baby may well need more milk at the moment to help him fight whatever infection he may have pending, and may want to feed more to help you build up your supply again after your bout of illness
**not v. wet nappies
This can be normal, as I say.
**boobs don't feel v. full
Normal!
** can tell dd isn't getting a large amount when she is feeding
How??!
**I express quite regularly so know roughly how much to expect
It is normal for expressing yeilds to vary - there are tons of posts about this.
Oh, and what a baby will take in a bottle after a breastfeed is no indication of anything, really!
However, I am not saying that you are mistaken in feeling that you are producing less as a result of your bug (though I do suspect it is not as serious a drop as you think), but I am saying this is a blip, and it is short lived, and your milk supply will bounce back as long as your baby can feed unrestrictedly. Milk supply at 7 mths is pretty robust and will not just disappear
