4 month shots

Did anybodies baby have a reaction to their 4 month vaccines? My little man finally got them yesterday (yes I know a month late) and had an awful night my mother in law is pretty sure he had a “fever seizure”.

He was fine all day yesterday besides of course the normal fussiness but about 4:30 in the morning i woke up to him on fire ! His temperature was 102.4 and I tried laying him down and his whole body was shaking and he wouldn’t look at me or respond he was just kinda looking around and his eyes were sort of rolling back :( .

I have 2 other kids and they never had any side effects like this .. only a slight spike in temperature.
