Hi there. What my pediatrician said was that the kids are pretty well protected after the first shot but she recommends the booster for children under 3 because, since they are so young, their developing immune systems need a little "reminder" as she called it. This is a really hard choice... to get the shot in the first place as well as the booster. All we can do is share our experience with one another so that we can all make the most informed decision. I got both shots for my 2 1/2 year old as she is at risk for seizure with a high fever (i have heard some kids have fevers as high as 104.8 with the h1n1 flu). I did hear, however, that the timeline for the 2nd shot was anywhere from 21 to 28 days following the first shot so maybe that will help you out with regard to the timing. Also, I am not a big fan of the mist for the younger ones and have heard a lot of stories like Fiona's about kids getting sick afterwards because the mist uses a live virus (vs. the shot, which is a dead virus).
