Agreed. My cephs grow in "bursts" of sorts. When I got mine originally, I kept them domed in high humidity and they didn't make a lot of moves. Months passed by. I picked up an eden black from a user here and heard they grew this impressive plant in normal room conditions so I decided to follow suit with the plant. I fertilized it with Maxsea 1/2 tsp per gallon once a week very light and it sat for about 3 weeks I think but then it began to grow. Matt (the admin of this forum) was telling me about how he was experimenting with filling the pitchers with a similar kind of solution and I thought it sounded good so I tried myself.
I filled the pitchers with solution rather frequently, as unlike the surface, the inside of the pitchers are much more resistant to that kind of treatment and if one does die, it just terminates the pitcher. Much safer. Anyway, after another couple weeks the thing just went crazy. It started with 5 pitchers and it was up to growing 20ish within weeks IIRC. I loved the response so I went for broke and moved all my cephs into the open (no acclimation) and let them get settled in. Filled those pitchers as well and my Hummer's Giants which had sat pathetically small followed suit and started turning them out. Took longer to get over the shock but the overall response was better. These days they're all doing well.
Fertilizing is risky business but filling the pitchers is a much safer approach. I use 1/2 tsp Maxsea per gallon and fill them up when I have time. Since your plant is small, i'd fill them with a small syringe and try to fill the ones I could from different points on the plant. If you're vigilant about it and the lighting is good, you may be surprised. It's not for everyone but I personally felt like it was a gamechanger. Some do osmocote pellets (just one per pitcher). I never did that because I felt it was too concentrated but some go that route. Good luck!
As Shadowtski said though, it's a fairly slow grower and takes some time but it growing leaves means it is growing and is likely to start making some moves soon. CPs need some kind of nutrient source in order to vigorously grow which it doesn't get indoors. Worms and the like are a safe approach. For me, I have too many to do stuff like that unless it's a very special plant. If you're able to crush some worms into power and add a small amount of water, that could be a safe alternative. When the plant does start growing in earnest though, it's going to fly. IIRC, mine also turned out new photo leaves before it began to put out larger pitchers
