Colief drops i use ready made formula cartons, instructions are 4 drops for ready made formula in warm milk for 30 minutes, at night this is really difficult to judge when baby is ready for a bottle. It says I can pre make up a bottles put 2 drops in each warmed milk and then store in the fridge to be used after 4 hours and used within 12 hours - after being in the fridge, the milk will be really cold so can I warm it up in a in bottle warmer before feeding?-(Even though it was warmed prior in bottle warmer for the drops to go in)
or any other tips using these colief drops? Especially overnight
