For teething we use Anesol (cant remember how to spell it!) plus Rosemont brand paracetamol, if you use the search function a recent post had lots of other suggestions for children who cant take Calpol . Not yet found a toothpaste that she doesn't react to though! she has reactions to Dairy/soya/wheat/gluten/additives/flavourings to name just a few ....
Hi if your Lo reacts to name brand Calpol try the chemists own brand as usually has less colouring in which some babes react badly to. My boys get hyper on Calpol but are fine on non brand paracetamol suspension.
I was told not to use Nurofen/Ibubrofen as this is not gentle on the stomach. I don't know what Disparol is but if it's aspirin based that's not suitable for children. I would be worried about giving part of adult paracetamol tablet!
I've not had prob with toothpaste but my toddler isn't cmpi & they hide milk products in strange places!
