My ds2 has been on omneo since about 6 weeks old. It was miraculous - prior to that a very screechy and unsettled baby though we never really knew whether the root of the problem was lactose or silent reflux. He's now 6 months and I'm thinking of moving to a more 'practical' milk for travelling in the summer [ie: one that doesn't have to made 'hot' etc.] Does anyone have any experience of omneo withdrawal?? Will the screeching return?? Is he old enough to tolerate other milks now? V grateful for any advice!
