Alfie had his MMR on tuesday. His legs swelled lots but have gone down, following day he was grizzly and upset and since then he has just got very clingy, not eating, upset, temperature. Runny nose and cough since today. Also he's not sleeping very well. This is unusual for Alfie he's slept 7pm-7/8am since 8 weeks. I have been told they can get rashes and things after as well but wondered what your children went through after the MMR jab.
