6 Day old Kittens Elimination Pattern

I have to 6 day old kittens and been caring for them since day one have not seen mother  but they were apparently left with placentas for a while as ants already eating the placenta.

They seem to be doing well. How often should the defecate in a day? One was constipated but finally went as I added olive oil to feed but fecal material still a bit hard so have diluted their milk. Other one seemed to go every feeding but bit paste like then gradually got more firm but recently stopped this morning and don't know if should be worried or it will go eventually. Their abdomins seem swollen but the other one eats more and more each time and is very active and purring while other one (who recently stopped defecating) is eating a bit less but still  2ml-3ml but not as active and purrs only sometimes.  Have been checking for signs of dehydration and give some pedialyte mix once in a while to keep hydrated. Yes i massage their tummies after feeding. Is it ok that abdomin swollen but kitten still defecates (at least once a day) and eats?

Thanks

You need to massage their anal region (not their tummies - or was that a euphemism?) before and after each feed.  I suspect there are plenty of videos on the Internet showing how to do this.  I believe the normal consistency at this age is rather like toothpaste, but it should firm up when they start on solids.

Without seeing them it's really hard to tell if their tummies are too swollen - a healthy kitten certainly has a rounded tummy.

Ah that was what I meant. I don't have any pictures at the moment. They all defecating fine for now. It is a toothpaste like consistency except the other one it is a bit more firm. Maybe just got worried because of the change in how often they went. Thank you.
