As others have said, go with you gut.
I forget all the exact shots now, but when my daughter, who was a preemie, got shots at 2 months, she had a slight fever. At 4 months, I gave her Tylenol before and there was no fever. At 6 months, I skipped the Tylenol before, still no fever. At 1, she got a doozy of shots, I think 4 or 5 total (the other times it had been 3 shots + oral vaccine) and she had no fever, although she woke up in the middle of the night screaming, something she never does. But she went back to sleep quickly.
So, I guess, it just depends? When it comes time for her to get her next round of shots, I will most likely go ahead, and again not do the Tylenol beforehand b/c I am not sure it's totally necessary.
Even some adults get fevers when they get shots.
How did she react when she received her other shots?
It's so hard making all these decisions! Best of luck whatever you decide.
