Lincoln has his 4 month check up

Lincoln went yesterday for his 4 month check up. He weighed 14 pounds and 7 ounces. He was 25" long. The doc said he is barring all his weight on his legs and they said that was advanced for a 4 month old. We did have some issues with how he focuses more on objects than people's faces and they held him and had me call his name and see if he would go towards my voice and he didn't. They want to send him to a NeuroMuscular doctor in Syracuse and have him checked. They think he might be either deaf in one ear or have something wrong with his ear and thats why he wont look at people because he just cant hear you or if it's something more. We are both worried but are hoping everything is ok with our little man. Other than that he was great! Growing like a weed and he is the cutest little guy ever but of course I think that, Im his mom lol!
