i saw one post about a lady with a 4 month old. it depends on breastfeeding etc aswell, i had a consultation with transform and they said they wouldnt go any further untill 6 months after i stopped nursing but i went to mya when my boobs got back to pre pregnancy n seemed normal to me, think id stopped feeding about 3/4 months before. and they didnt see a reason why i had to wait any longer. my lil lady is 10 months now and i stopped feeding her about 5 months ago. hope that helps! xx
