Yes, stinging. That is a huge problem. With my son, anything that stings, he screams. So that limits so much what cream we use. Have you tried moogoo. It is an all natural cream made her in Australia. Really good for my son it does not sting. We found the moogoo for the scalp works the best all over his body. Used it on his scalp and it cleared his psoriasis there (or could be a coincidence I suppose) But it is very expensive. But it does not sting and if anything stings he won't use it.
Also, know it sounds weird and alternative, but cacao butter, melted over a bowl of hot water, really moisturising, all natural, not that expensive and you smell like chocolate :). Or coconut oil. We use it in the bath, my son comes out really moisturised after that. (but careful about it blocking the pipes) or can use it straight as a moisturiser, a bit oily, but leaves the skin soft as butter, like the cacao.
