It's nearly 2am and my dh and I have been up with an extremely grumpy 12m old since 11.30pm. She had her MMR 6 days ago and although she has never been a great sleeper, she has been really unsettled and awake a lot at night for the last 4 or 5 nights. She is fine during the day apart from off her food a bit and a runny nose. Has anyone else experienced this? We weren't warned about this as a possible side effect! Thank you in advance.
