After baby visitors and shots

Randi
Ok ladies, I am starting to stress a little. We live in Colorado and our families are in Texas. We have several groups of family that have planned trips within the first couple weeks after my due date to come visit the baby. Here is my question: Since they are staying for several days (not just popping in for an hour), and probably want to kiss all over the baby, is it over-doing it or too anal of me to ask that they have Dtap and the flu shot before coming? I feel like it would be different if it wasn't flu season or expected to be a big year with a lot of pertussis, but I also know I will be the mom that freaks when they are kissing all over her and she is not old enough to get shots yet. How are you handling it?
