My better half discovered two kittens on the sidewalk while taking out the trash, still connected to the placenta and everything. Queue montage, humane society visit, paperwork, waking up every two hours, one of the kittens passing etc etc etc to one week later and I am still having a very difficult time bottle feeding the surviving kitted.

I do NOT know what I am fucking doing wrong with these feeding nipples but the cut in them is either too small so that he is not getting anything from all the nursing he does, or its too big and milk bubbles out his nose and sometimes he sneezes. This happens at least a couple times a day, and since I've had him. When we took him to the humane society they looked him over and said he was healthy and nothing was wrong with him. I expressed my concern about this and that he may be aspirating the formula but... I dunno, the hole in the nipple THEY provided was MUCH bigger than the hole in the nipples I've been using.

For the first few days with that nipple, the formula wasn't bubbling from his nose and he wasn't sneezing it after feeding, but now he is occasionally. Do you think he's now nursing too eagerly/too quickly? He's still gaining weight, he isn't lethargic, he eliminated before every feeding and it's clear, and he voids his bowels once or twice a day and it's normal and pasty but... I'm super concerned about this feeding thing! D: I have 6 nipples and all of them seem to either be too small to get him to stay interested in suckling or too large and it bubbles out his nose sometimes. I don't know if thats normal and I shouldn't be so worried or if I'm seriously contributing to the possibility of pneumonia by not doing something right. D: !!! I mostly have him flat with his head slightly elevated and craned when feeding, and sometimes he's just so animated that I have to roll him into a purrito so he doesn't crawl all over the place and claw up fy hands.

Any advice or pictures on how big or small to make the nipple hole would be great, or better holding/feeding techniques? Pictures would be best. Ive tried pins and I've tried snipping an "x" with scissors and I've tried just one slash over the top too. Please and thank you.
