I would like to say lazy, Anti. Gabriel is showing signs of delay in other areas as well. He doesn't babble, doesn't use any gestures. He doesn't use a pincer grasp, his only "play" with toys is putting them in his mouth. He also only rolls in 1 direction. The main areas that I had concern with, were his communication, his gross motor development and attachment. This baby could care less if I leave the room, and when I return, IF he notices that I have left, he smiles the same smile that he would give a stranger walking on to the elevator. I spoke at length with the evaluator about this, her thoughts were that he doesn't have a lack of attachment, only he is very confident. She pointed out a few little things that I never noticed him doing that indicates attachment. Autism was quickly removed as a possibility as he is a very social little boy.
Anti, have you looked at the 'Ages and Stages" questionaires? It will do 1 of 2 things - reassure you, or freak you out. If you decide to look at them, keep in mind that not all babies can do ALL the tasks, at that age.

This is a link to a fairly good one that has the questionaires for ALL ages. I found it helpful to look at the 6 and 8 month ones to see all the things that Gabriel CAN do. I found it reassuring that while he is doing things slower, he is still progressing, and will likely not have a long term issue.
Hope This helps, rather than concerns you.
And thanks Yazzy. I try not to blame myself, I know all babies do things at very different rates, and nowadays there is so much pressure on kids to do things faster/better. My FIL didn't walk until he was 2 and no one said he was delayed. I am trying to focus on the things he can do, rather than the things he cant, especially now that I know that there is nothing we CAN do but wait and see.
Lief: Hope your little guy feels better soon! Its very easy to call an ear infection teething, the symptoms are SOOOO similar!
