So when I took my son in for his 1 year checkup and shots, I was told he wouldn’t need another round of shots or a checkup until he was 18 months....and then I learned that he should’ve had them at 15 months. He’s my first born so I had no clue and didn’t really pay attention, just took his doctors word on it. Is there going to be a problem with his vaccinations now or should I not even worry about it? Obviously I will talk to his doctor about it at his 18 month appointment, but I’m a little concerned right now
