You are sure to feel concern about the nutrition your baby gets for physical development. The question is – why do you neglect the nutrition for mental development? Presenting adequate stimulus for your baby helps his/her mental faculties to develop.
You may read books to your baby, or let him/her learn new things using flash cards, or use multi-sensory learning methods too. Your baby can read from a very early age; all you need to do is provide him/her the basic tools for learning.
Your role involves presenting stimulus and providing the right learning environment. You also need to make sure that the little one is having fun. Every baby has a specific pace of learning, and you need to be patient.
