It is very encouraging to see Mikan so interested in his baby brother. What may appear like normal curiosity in the video below is actual such tremendous progress for Mikan. For him to engage with other kids and initiate interactions is a great breakthrough in his socialization skills. The appearance of Baby Drexler has reminded us of how far Mikan has progressed and made us realize how important his siblings are for his development.
BTW, Mikan nicknamed the baby "Pancakes" before he was born.
