Once your baby turns six months old, it is time for them to be introduced to the world of food that should include solid as well as liquid food. But that does not mean that you need to stop with the breastfeeding , since that is the richest and the safest source of nutrition for your baby.
Also, immediately switching to whole milk is not advisable since that might result in an upset tummy for them since they might not be able to digest all that heavy stuff just yet. It is also important that you wean off the liquid food slowly and steadily from your baby's diet since a growing baby needs more nutrients than liquid foods provide.
