My nephew is very sweet and loving. He loves my youngest daughter soooo much you can see it in his face when she walks into a room. He seems to be developing normally as far as milestones go. He says "mama", "dada", "Hello", my daughter's name, "Ball", and "Oh no!" Though, when he is around other children his age they all seem so much more responsive and developed. I was at his house recently and there were other toddlers his age and younger. When I sat on the floor with the babies they were all vying for my attention and trying to show me what they were playing with except him. The parents of the other little ones kept saying, "Look at Kyle, he is in his own world." When you call his name he acts like it means nothing to him. He will watch his favorite show for hours, rock back and forth, and act like no one else is in the room. He is so active most the time and never sits still for even a second. Always kicking, or rocking, or generally throwing himself around. He will readily give kisses and hugs, if you can catch his attention, but does not like to be held for more than a few minutes. He does look at my daughter a lot and touches her face and hair and always wants to hug and kiss her. He will also touch things that are hot or walk barefoot on ground too hot for my feet and not even be phased. He walked early and loves to play with toys. His motor skills seem more than fine. Hmmm ... he cried a lot as a baby and they thought he had colic, but his symptoms were not typical. When he was really little he would not grip your finger or things that were put in his hand. That is all I can think of for now. What do you think, I am worrying for nothing?
