I ' m happy to report that Mackenzie 's visit yesterday to the pediatrician went better than I expected . Knowing that she was about to get a humongous needle in her thigh made it particularly excruciating to stare down at her smiling , drooly little face while we sat in the waiting room , but she took it like a champ . We made a last - minute decision to decline the Rotavirus vaccine , so Mackenzie just got her DTaP yesterday . Our pediatrician was comfortable with this decision , and she did n't even make us sign the " I ' m a bad parent " memo that I ' ve heard that other doctors require .
