DD (2.5) was sick a couple of times Wednesday and Thursday morning last week. Since then she’s been fine, seemed back to her normal self from Friday, was running around a playground yesterday and was at nursery today. But she’s just been sick again (quite a bit more than any time last week). Is this just the same bug continuing? Is this normal sometimes, there was 4.5 days between the last sickness and tonight. She seemed completely fine, went to bed fine, but woke up crying after about an hour and then was sick. She’s now just gone pretty much straight back to sleep, no fever (didn’t have one at any point), no other signs of illness at all.
