Not sure if I'm mentalling about nothing here. DS (16 months) has been ill with bad cold for past couple of weeks. In the past week or so his skin has had red blotches that have come and gone. I'm not sure if this is because of his cold or because it is cold outside and the change in temperature or if it could be that he has slapped cheek syndrome. If he has it it's very mild. I'm going for my 12 week scan and bloods on tues, should I just mention it to them then when they do the bloods? Or am I just unnecassarily worrying (I am a worrier!). Any toughts?
