Lo is 1r months old. Had his mmr 3 weeks ago. Been OK, had the measles rash now gone and no temperature. Friday night he was sick overnight. Fine through the day then sick again 530pm Saturday night then fine. Today he's hardly drank anything. Kept refusing it. Had milk tho before bed as he normally does and just before putting him in bed he's sick again. His dinner which he ate most of and milk. He's had a reduced appetite recently. Mmr side effects do not state vomiting. Waiting on a gp callback though could be a few hours and he's fast asleep. I've done a dream feed type thing and given him water as worried he's not had much. Anyone else had this? He had a sicknesss bug in April, we all did so I doubt it's the same plus we've not caught it. I'm so worried. Oh to add he's apparently been dry heaving a lot today too
