my little boy was born at 25+6 and we had his paediatric app on the 8th on November and was told we could wean start of dec. as he is over 6 months now, Adjusted he only 11 weeks tomorrow, but he has been getting breast lmilk in his little tummy for 6 months, we have tried him with banana and he absolutely loves it, So taking things slow. If in dooubt ask ur paediatric dr or gp.
