**Disclaimer: this is not a discussion about vaccinating vs not vaccinating, we vaccinated our son because that's our choice**

My two month old received his first round of vaccinations on Wednesday and is still really cranky and just acting different, he will be sleeping while I'm holding him and all of the sudden he starts screaming when a noise wakes him up that has never bothered him before (ex. our dog barking) or I slightly change positions with him in my arms. Is this normal or has anyone else experienced this and how long does it last? We were using Tylenol Wednesday and Thursday because he had a low grade fever and was really clammy, today his temperature is fine and he is not clammy any more.
