The homeopathist recommended a 3-week dairy-free trial for DS, so see if this improves his eczema. He is therefore having various milk/yoghurt replacements, incuding soya yoghurt, margarine and custard. However, another mumtold me today that you must be careful with giving soya products to boys, as it can make them infertile! Eeek! Does anyone know anything about this? Any help/advice appreciated...
