Visit Dr. Anthony Calibo of St. Luke's QC, Dra. Tita Uy of Capitol Medical Center, Dra. Patricia Balingit at Northridge Plaza near Congressional Ave. You can know more breastfeeding advocate doctors if you join Breastfeeding Pinays group :)
In case you're residing the Laguna area, I'd recommend my pediatrician, Dra. Tababa. I also had a hard time looking for a doctor that's a breastfeeding advocate and was delighted when she ordered me to keep breastfeeding at least 6 months.
