Playing with your baby and seeing his face light up with a smile every time he is happy is probably the best part about being a parent. You would have also noticed that your baby is happiest playing with you or the primary caregiver rather than anyone else. He looks more relaxed and willing to respond. This is because of the bond that has been built between the two of you while you were taking care of his needs.
What you need to know
