Many people ask me for a schedule and I decided to write down what I use as a template but not a hard fast rule in feeding mini kids (pygmies, mini mixes or nigerian dwarfs).
Week 1 1-2 ounces every time hungry (usually every 2-3 hours) can have up to 4 ounces especially if left longer between feedings.
Week 2 2-4 ounces every 3-4 hours (like feed at 6-9-12-3-6-9)
From then on out I increase the ounces once per week as needed.
Week 4 I reduce the amount of feedings to 4 times a day.
Week 6 Reduce feedings to 3 times a day (by this time they are at 6-8 ounces per feeding)
Week 8 If weaning reduce down to 1 feeding a day and reduce amount
Hope that helps. Its not an exact science I just try to gauge how the kid/s are doing and if they need more or less. They need more if they seem tired or listless. Feed less if they don't seem to want all the bottle or want to skip a meal.
