Ds is 8 months old. He had a cold last week and had one day where he was crying all of the time except when he was on calpol. He's still got quite a runny nose now but he'd had that prior to the cold and we put it down to teething - he doesn't seem to be showing any other signs of teething at the minute and he has three teeth through which were fairly straightforward. He's seemed quite fretful at night for a the last week or so sometimes going to sleep ok but then waking - not always for too long but crying and either settling when i comfort him or give him his dummy of just settling himself after a few seconds. This morning he was crying on his way to nursery and nursery said he'd not been his usual self all day and at one point had a bit of a temperature. He was ok this evening but is generally more fretful. He's usually such a jolly and giggly baby and I don't know whether its down to teething, whether its some sort of post-viral thing or its just his developmental stage (not the temperature bit!) Does anyone have any ideas? I feel like i'm always worrying about him at the moment.
