If you're worried about your baby not getting enough protein(very important for babies), you can syringe feed baby food. It's what I'm doing with my little one since he's not eating as much as I would like.
I go with 1:1 ratio of store bought organic chicken and veg stage 1 baby food, and home cooked spaghetti squash blended until smooth. In that I put Carnivore Care in the whole batch. I got it from a local vet, but you can buy it from here:

I put just over 1/8th of a tsp in for every tsp of food. It's packed with protein, so it's great for dragons that aren't eating their bugs.
From there I split it into 2 batches and mix in his calcium in one. It should be about 1 part calcium to 3 parts food. (1/3tsp for every tsp). He gets that for 1 feeding 5 times a week. The other is plain food for his other feedings, and 1 time a week he gets a little bit of multivitamins mixed in(again a 1:3 ratio). I only give multi's once a week because the Carnivore Care has a lot of vitamins in it. If not using Carnivore Care, do multivitamins 2x weekly.
And from there you syringe feed. You can put a little on the nose and lips and they should lick it right off. Keep doing that until they stop eating for at least a minute. My boy eats as much as 1/3 of a tsp per feeding and I try to feed him 3x a day with crickets between if he'll take them. I offer veggies, but he won't take them, and since I know there's lots of veg in his baby food already I'm not super worried about it.
Hope this answered your syringe feeding question. You can do feed without carnivore care, but I would go straight chicken and veg and no squash mixed in.
