My sister is currently weaning my 9 month old niece. I say 'weaning' but my sister only ever gives the baby the same pots of fruit puree. Along with breast milk there is nothing at all in the baby's diet. My sister just says breast milk alone will do until 12 months. My belief is baby's need a varied diet from weaning age so they get all the nutrients and to avoid fussy eating further down the line. Who is correct? my nephew who is only 6 weeks older is on a very varied diet.
