There is lots of evidence and research now why you shouldn't start solids too early, and I am sure 16 weeks IS too early. Can't see the point of starting on baby rice - milk is so much better for them, full of calories and nutritionally complete - why complicate things by starting solids?? Can your HV offer any (research based) evidence that by starting rice it will help the wind/puke thing? If not I would give it a wide berth. Anecdotally from friends who did the traditional weaning thing, babies often get more wind, plus constipation........ Keep persevering with the milk xxxx
