Take raisins in a bowl and add 1/2 cup hot water to it. Let them soak for 30 minutes.
Rinse and peel the apple. Remove the core and chop it roughly.
After soaking time, the raisins will absorb water and swell.
Add the raisins with the soaked water to a blender jar along with apple pieces and pomegranate arils.
Add around 1-2 cup of boiled and cooled water to the fruits in the blender jar.
Pulse multiple times to extract the juice from the fruits.
Strain this juice through a strainer.
Serve the strained juice to the baby. You may dilute the juice further with water as per the preferred consistency.
