Since 1995 Janaki Costello, has worked with new mothers in the field of birth and breastfeeding as an International Board Certified Lactation Consultant and a Certified Childbirth Educator/Doula. She is pleased to focus on in-office consultations as part of East Bay Lactation Services after many years of home visits in private practice.

Her areas of expertise include: multiples, breast surgery, adoptive breastfeeding and relactation, ankyloglossia, slow weight gain, painful breastfeeding and latch refusal, as well as all aspects of normal breastfeeding management.

Skilled at helping all members of the family, Janaki assists partners, grandparents, siblings integrate the new baby and resolve breastfeeding problems in the context of the family unit.

She is the mother of three adult (breastfed) children and four breastfed grandchildren.


Janaki only sees clients in the office.

Janaki was able to involve my husband very skillfully, which made a huge difference and helped both of us feel as a team in a situation that could have easily excluded him. I have recommended her to several pregnant friends and will continue doing so. Thank you, Janaki!

I was depressed and desperate, on the verge of giving up. After one visit with Janaki, we were breast feeding! Janaki is an amazingly knowledgeable, talented, kind and caring teacher. She has also been available every step of the way, when I had questions or concerns. Janaki gave me the ability and confidence to successfully breastfeed my baby. I give her my highest recommendation.
