1 Year Old Milestones

Well Nehemiah will be 1 on May 20th i'm so excited. He was a preemie (i gave birth 1 day into my 24th week) so he's behind some but the Dr said he should catch up when he's 1 going on two. What are some of the things that a "normal" 1 year old should be doing?

Here Is What He's Up To
*He just started holding his bottle like 2 weeks ago
*He can't crawl yet
*He can only sit up for a short time
*He can put his paci in his mouth
*He plays with his hands
*He smiles at will
*He plays with his feet
