I've been gone a long time but see that I can still offer at least a tiny bit of advice on this. I always fed my babies proper sized meals DAILY. If you're not feeding daily that could explain the slow growth you're experiencing.
Once baby hits around 12 months old then you can adjust according. I've raised bosc monitors from all stages. Some were fed every other day, others everyday. I allowed them to tell me what they needed. All monitors are gluttons. At least healthy one's in my experiences.
The key to feeding daily is proper portions.
Hope this helps.
