Thanks for the useful information, Chris! When we found the tick on my 9 month old son, we had a lot of people tell us that there was nothing to worry about because "it looked like it hadn't been attached for very long", and the probability of him contracting Lyme from it even if the tick was a carrier was "very unlikely". However, when talking about your first child, and under a year old, "very unlikely" doesn't really mean a whole lot to me. If you have any symptoms as Momay has said, get it checked out by a doctor.
