When raising baby gachas, don’t put food into their inventory. Drop stacks of berries in front of them. The difference will be 5 berries as opposed to their weight being full so for eg 5k berries instead. And they do consume food fast. Also putting them in kangaroo pouch of mate boosted pair helps to slow consumption rate I believe.
Very easy to raise, just drop tons of stone infront of the baby. It will keep picking up stones no matter what it's weight cap is.you can fill unlimited stones like this and will never have to hand feed.
