Pacing means responding to the baby during a bottle feed, including allowing pauses and an end to the feed when the baby is ready. The Australian Breastfeeding Association describes supported positioning and controlling bottle flow. Read its full technique and the linked guide before trying to interpret the label as a set of instructions.
It is not a competition to make a bottle last a particular number of minutes. A timer cannot tell whether the position, flow or response to cues is appropriate. Record the amount taken separately from the amount prepared, and keep any individual feeding instructions with their source.
