If you have given milk and fluids, you have done well as a parent. You can start child on high fiber feeds like oats and give her apples and bananas. If the constipation is cause by cerelac, stop that formula. Give her chapati, dal, rice. You may add ghee to these to fortify them. Rub your child's belly in clockwise direction. Give some times of 1-2 days for constipation to settle.

Plenty of water..high fibre diet..green leaf vegetables, legumes..this will do..reduce milk to 300ml/day maximum..
