Yesterday morning, dd2 (12mths) vomited quite spectacularly 3 times. She then slept for most of the day, but in between sleeps she would have moments of being quite jolly and like her normal self. At various points though she would suddenly start crying, writhing around, arching her back, and nothing I could do would console her. Didn't want to be held, wouldn't suck her (usually beloved) dummy. This would go on non-stop for about 15-20 mins and then stop, at which point she would seem exhausted and just sit quietly on my lap or fall asleep.
She started again as I was putting her to bed last night, but breastfeeding her calmed her immediately and she then slept well (after a dose of Nurofen) until 3.30am, when she woke and started screaming again. I fed her again, which again calmed her.
At 5.30am she woke again (usual time for waking) and dh brought her into bed with us - I fed her again which stopped the crying, but because I had fed her at 3.30am, there wasn't much milk, and as soon as it had run out she started wailing and writhing again - this went on for about 20 mins.
She woke at 8.30am and seems absolutely fine, but I am worried that she might get another crying fit.
Has anyone got any ideas as to what it could be? Teething maybe - one of her cheeks is a bit flushed (but would this cause the vomiting?). Was a bit worried it might be connected with the MMR that she had a week ago, but the symptoms don't seem to be a common reaction.
Not sure whether to take her to the GP as she seems ok in between screaming episodes.
