Need some advice on when to schedule our 12 month vaccinations/check up. DS didn't have a bad reaction to any of his previous vaccines, but I have heard that 12 months can be pretty rough due to MMR. (I'm anticipating 8 immunizations at this appointment because they should have influenza available!)

His birthday party is currently the day after his shots. I'm probably worrying unnecessarily, but would you keep the Friday appointment, or delay until the following week? I could handle him being tired/grumpy on Friday, and can even take off from work if daycare says he isn't feeling well, but I really don't want him to be miserable for his party on Saturday.

The current plan and limitations:
Wednesday - not allowed because he is not "officially" 1 year old yet. (so frustrating!!)
Thursday - he is officially one, but doctor is out of the office today
Friday - appointment and vaccines scheduled at 8am, will go to daycare after. In-laws also arrive today from out of town.
Saturday- small birthday party with family/close friends
