DS2 is L.Intolerant and has been on neocate since 3 weeks. He is now 15weeks old and a whopping 17lbs ! Sleep has become elsuive and he is waking earlier and earlier. Do I need to be careful weening given allergy to lactose ? Is baby rice safe ? Do they ever out grow L. Intolerance ? Would love more sleep but not surprised he is sleeping badly as Neocate seems so watery compared to Aptamil for example. Help please....
