While your child loves to play with you, there will be certain times when your baby plays alone. This is most likely to happen when he is content with himself on all fronts, like, he is well fed, he is comfortable and the room environment is most appropriate for him.
At this point, you can expect that your baby might want to have some lone time, playing. You will notice your baby playing alone in his crib as well. While it is important to give attention to your baby at all times, if your child displays signs that he is content in playing alone, do not try to stop him. This is just another part of his healthy development. Without you, your baby can play alone for 5 minutes.
