Help: Queen stopped eating...

I am fostering an queen (about 1.5 years old) with two now 10 weeks old female kittens...

The first few weeks all were perfect...

Then they all started sneezing and one kitten got a really bad inflammation of nictitating membrane (in the left eye) but is now almost back to normal ( see http://www.thecatsite.com/forums/sho...d.php?t=123885 )

The other two had a very mild inflammation of nictitating membrane in both eyes... so they were all getting: antibiotic (Clavamox - amoxicillin trihydrate/clavulanate potassium (oral drops)) in the right doses - now the dose has finished...

And the mother has a mild/moderate inflammation of nictitating membrane in both eyes - while both kittens seem to be OK.

(is it a bad virus or what?)

they are all still sneezing...

But now I am completely sure that the queen has stopped eating for a few days! (Queen is still lactating / or at least the kittens are forcing her...)

Obviously #1 concern is that she is not eating (she did eat the same food before and kittens have and are eating this wet and dry food all the time...)

Not sure what to do...

Please help...

Thank you all...

update: the queen (she is not feeding them anymore, so I guess the mother?) started eating - I think it was a side effect of the antibiotic
