Totally understand the concern, so many of us worry about this after breastfeeding and you are definitely not alone in asking. I don't have a specific contact on hand right now, but maybe try asking in the confinement nanny or postpartum massage groups on Facebook as a lot of mums there share home-based therapist recommendations. You could also check with your postnatal massage auntie if she knows anyone who specialises in bust treatments lah, they usually have a good network. Hope you find someone good soon!
