My son is almost 7 months and has an appointment this coming Wednesday for a check up and I need to get him vaccinated since he is behind (skipped his 4 months because of problems with the doctors) and it's at 4pm and I was just wanting to know if I should get him his vaccines this appointment at that time or wait for his other appointment the middle of this month and its in the morning. I'm kinda aiming for morning just because I worry about what if he has a fever at night?
