I am by no means an expert, since I've only had my first carpet for 6 months, but I feed her an appropriate sized prey item every 5-7 days unless she is in shed. She's a 2018 baby, so not even a year old yet. If I happen to have a bigger item that she takes it down, I wait a day or two longer. Generally in my minimal experience, hatchlings and young snakes slam and process food like mad, they're trying to grow. I don't usually weigh my prey items. I did for my carpets first 1-3 feedings because she was so tiny and I was afraid of over-sizing it. I've since learned she can take some pretty big meals.
With my BP I actually spread her feeds out to 10 days when she turned a year old. Likely will do the same for my carpet down the road here.
You're probably good to keep feeding whatever is the appropriate size every 5-7 days for the next 6-7 months or so.
