Harry had is 1 year injections at 2pm this afternoon, and has slept since 2.15 and is still asleep. Normally he only sleeps for an hour, but I didn't want to wake him as he is teething at the moment, is it normal for them to be sleepy after their 1 year jabs??

I know I'm just being paranoid its just because its the MMR jab hes had and I just worry lol xx

I wouldn't worry Hun, they all react differently to injections.
I would think tho that this is more the teething or just being tired. The effects of mmr don't tend to happen until 7-10 days after the event.
