Kittens not gaining a whole lot anymore... supplement?

A couple of the kittens only gained ten grams in two days, and one gained nothing from yesterday to today. I want to supplement, but I have been having a really hard time getting them to accept the bottle, and I've tried the corn syrup trick. The nipples seem way too large for their mouths, and I'm using the narrowest one.

Any suggestions are welcome...

Oh, weights at 11 days (today) are:

190g
240g
205g
215g
175g
150g

Well, I spoke too soon. A couple of them just learned to suckle on the nipple, and with three of them, we kind of compromised and I dropped it on their tongue as they swallowed. There was only one that wouldn't take it. I was rewarded with one of them falling asleep on the nipple, purring little tiny kitten purrs.

So, for those of you out there who are trying to do the same thing, it just takes persistence. Eventually they figure it out! This is the 4th time I've tried today, so keep at it... I also let them smell my face and I coddled and talked to them before I tried to give them the bottle.

How are the little ones today? Sarabi's litter that I weighed seemed to vary in their weight gain. Turned out they had a bad case of worms. Maybe you can take some poo samples to the vet just to be sure!

also you can add Nutrical( come in gel form) to the KMR to help stimulate there appatite. good luck and bless you for sticking to it!

Well, they're getting too big to weigh...

They seem to be doing fine now. I have never seen a poop, except for the first day's merconium. How can I tell if a kitten is constipated?

KMR will constipate kittens. make sure there getting enough fresh water as well. you can dilute the KMR with a lil bit of water too, to help up there water intake.

I add mineral oil to the KMR to help with the constipation, and they are too young to be drinking on their own yet. They seem okay, but they are only two weeks old, so it's hard to tell.

you said you never saw a poop. have you tried to stimulate them after feeding to go?

Yep. They go pee fine... just never seen poop! Weird, huh?

that is weird!!! is momma still with them, or are you momma? if momma is still with them, she maybe taking care of it before you can see it?

Momma does most of the work. I just supplement feed because she's a tiny cat and I read something that said it's helpful when there are five kittens or more, especially when momma is small.

I'm not too worried because mom is probably taking care of it. But one would think I would see at least one poopie.. They sure are starting to smell a bit... despite me changing the towels twice a day.
