Helen - I'm all for a pain killer with a sedative side effect when it comes to teething!
Well me too, but the nanny state we live in doesn't agree!! There are definitely times that we would give Medised, but I feel guilty. I have only ever used it once on a flight to Australia, and we had to lie to buy it.
I've not seen any evidence of Calpol making LOs sleepy either! I give it at any NW where I can't figure out what the problem is, and it makes no difference!!
