It is a lovely photo! Will got a cold at 3 weeks and we used a vapouriser which seemed to really help. The pharmacist also said we could put some euky bear rub on a hanky or something (but out of reach and definitely not on skin) and that would help. He said the over three months thing on the rub was due to the skin being too delicate but the actual ingredients aren't harmful as i thinks its fairly natural stuff.
Hope he's better soon.
