Over the last week DD (almost 1) has been throwing up little milky bits. I've noticed at times she's sticking her fingers down her throat, making herself gag so I've suspected that this has been the cause of the sick when I'm not looking. I also put the sticking of fingers down throat to teething. (Not sure if I'm right or not)
Anyway, last night she was properly sick and felt very hot. She had only a very slight temperature. We stripped her off and she cooled down and was fine for the rest of the night.
This morning she hasn't been sick again but has had a very upset tummy instead.
What I'm not sure of is if these are all related; if the initial small sicky puddles were a forerunner or not.
Or could her sickness last night have been caused by overheating? We went for a walk yesterday afternoon. She was in the backpack with a hat and sunshade. She was never in direct sunlight for long.
Sorry if this doesn't make sense. I'm not used to her being ill 
Oh and I can't get her to drink any water. She's has a few mouthfuls of weetabix and a tiny bit of yoghurt this morning.
