I have worked in dental for 18 yrs. now, I am not a Dr. but I do know a bit...firstly, DON'T worry! The first 2 teeth may look huge, and in your sons case, may look bigger than normal because of family history of larger than normal teeth. (if this is the case) Or because you've only seen that cute gummy grin till now and may seem enormous to you! And secondly, all baby teeth will have gaps between them..this is to make way for the bigger adult teeth later in life..and same thing with the gap, if some members of family have had this, than possibly he will..but that's a long way off..around 6-7 yrs. is when you will see his adult front teeth, and even then, if you want to have it fixed, your dentist will have you wait until most of his adult teeth are in, and that will be around 12 for when 12 yr. molars come in, and even later for wisdom...a good dentist will have you wait, because as all teeth are coming in, they push and crowd each other around, and you should wait to see how much the gap will be "naturally" closed or affected by the teeth themselves. Putting something to cover the gap before then, which is costly, or braces which is even more costly, can be ruined by bigger back teeth coming in...around 12 is a good time to consider orthodontics. (braces) As far as taking him to his first trip to the dentist? Some say as soon as he gets his first teeth..which is good to get him comfortable with going..if you start now, by the time he goes in for braces? He will be a pro, with no fear! They don't do much of anything at first..just look..some say wait till about 2 when he can understand more, and communication is better..that's best I think..I started mine around 2...good luck, and most of all no worries Mom! :) And above is all just my humble opinion! Hope it helped!
