Sounds like you are doing everything right. I know how stressful it can be, especially when they don’t want to eat. Lucky is my little girl, she turned 3 weeks old Monday and was 3 days old when I brought her home. When I first brought her home, I had to force feed her too because she would NOT eat. She was so scrawny, and is still small for her age, but she’s finally gaining weight at a good pace. What brand of formula are you using? I started out with Hartz and am in the process of gradually switching to KMR and have found that she likes the taste of KMR much better, and is a lot more willing to eat it. She also has put up a huge fight because she is teething, and was refusing to eat too much for a couple of days last week. There are lots of different things people recommend if he still hasn’t pooped after a couple days. Some people stimulate manually with their finger under running warm water & say that is more effective than a cotton ball or cloth, some people have tried inserting an infant thermometer with vaseline to stimulate them to go, or even putting a few drops of vegetable oil in his bottle. I found a solution to Lucky’s constipation accidentally, I bought her this supplement called Nutri-Cal Kitten, it’s a high calorie gel with vitamins and nutrients, and gave her some of that since she wasn’t the best eater, and that made her poop a lot! I wouldn’t be too concerned about the lack of poop yet, if he’s not eating a lot then it totally makes sense why he isn’t pooping much.
As for the sleeping thing, I think it is normal that they change positions a lot when they’re sleeping. Lucky does the same thing, every time I look at her she is in a new position!
Oh and one more thing…are you feeding him from a bottle? I have found that Lucky absolutely HATES drinking from her bottle & refuses it, to the point where I have scratches on me. She is 3 weeks old and still drinking from a medicine dropper. If he is refusing the bottle, try the dropper? He may like that better. It really is a matter of trial and error, keep trying things until you figure out what works for you guys! I really hope your little guy starts eating more & doing great! Keep us updated and we would love to see pics if you have any! ๐
