Ds had his 2nd (of the 3 in MMR) seperate jabs yesterday, as soon as we left the hospital he was given a snack and then we drove home. On arriving he woke up and was sick in car seat and again at bedtime after last milk bottle and again at midnight! Is this a reaction already to the jab? On Friday attended first ever Xmas party and ate a load of junk and was very hyper all afternoon, would there be a reaction to that? Seems better toay, well hasn't been sick so far tg!
