So far my daughter age 5 has only gone in every 3 months. She had a big sinus infection that went to her chest and started to turn into pneumonia in late September so we will go back for a check-up 6 weeks after her last visit. She hasn't really been very sick so far (other than common sicknesses and this last cold mentioned above) so that is why she goes in every 3 months. When we go back for the follow-up it will be interesting to find out when they want her to come back again.
Maybe the CFF is starting to change their suggestions?
