I have three kids and all I can tell you is that each one took their path with teething. The first two kids just GOT teeth, it was like they would wake up and there would be more teeth!! They started teething at four months and had a full set of choppers at their first B-Day party. Well baby #3 made up for the ease of the first two. On his first B-Day he only had the one bottom tooth and it took like months to get that one! He is now about 3 (sep 16) and finally got his last two year molars! So comfort him the best you can and use the frozen washcloth and binkies too if he takes one. Good luck and remember even after those first whites break thru the gums there are several more to follow! I know that the eye teeth and molars are the hardest, at least at my house they were.
