Sarah Tyack RN, BSW, IBCLC

Serving the San Francisco Bay Area, Oakland and the East Bay
Practicing Virtual Lactation Consulting Internationally

I have over 25 years experience working as a Registered Nurse and Lactation Consultant in hospitals, clinics, and private practice. My clients want to be the best parents they can be. I can help you feel confident enough to feed your baby in the way you choose.

I have a belief that mothers are strong. They find their strength at different rates and in different ways. There are times when new mothers feel overwhelmed with information and then question their ability. New moms receive so much information from friends, family, the Internet, and their doctors. While some of it is good advice, some isn’t and when new moms are sleep deprived, it can be a difficult time to tell fact from fiction. What works for one mom and her family may not work for you. I can help you develop and implement a plan that is tailored for you and your family. I’m always amazed and humbled by the resilience of new mothers and am honored to be a part of the process.

  • I emailed Sarah very late one Sunday night after seeing six other lactation consultants and taking my baby to see a pediatric occupational therapist because I couldn’t get my baby to breastfeed. None of the techniques or exercises suggested were helping us to breastfeed and I was getting to the end of my rope. Sarah responded to my email first thing the next morning and came to visit me that same day. She had us breastfeeding within 60 seconds.

  • Sarah responded to my email really fast and even gave me a call right away. After talking and assessing that I did need immediate help, she made time to come to my house the next day and answered not just breastfeeding questions/concerns, but even other postpartum or health/motherhood questions I had.

  • Sarah is wonderful, calm and completely reassuring. I was in the thickets of the hardest week of my life when she swooped in and by Wednesday evening I felt like I was nearing the other side. I really don’t know how to thank Sarah enough.

  • A visit from Sarah definitely feels like THE turning point in my journey of breastfeeding my son. I was struggling with many issues and a lot of doubts. A couple of visits to the lactation clinic did not seem to help much. My son was 4 weeks old and that was when my mom and I decided that a house visit by a lactation nurse might help. Then I stumbled upon Sarah through Yelp and I do thank my stars I did. She was so warm and friendly. She gave me the confidence to breastfeed and spent a couple of hours training me and my son. She showed me so clearly what had been going wrong so far. I definitely recommend Sarah to any mom with breastfeeding issues.

  • Sarah is compassionate and so very knowledgeable as a lactation consultant. I sent her a message after having soreness and an infection. I was very frustrated. She called me right away and spent 2 hours with me on a Saturday to practice latching. She was so friendly and supportive and I feel like I can reach out to her again with any other issues. She is definitely an amazing resource to reach out to for breastfeeding help. If you are having ANY issues call her immediately.

  • My husband and I spent a good chunk of the morning trying to find out where we could get access to a lactation consultant on the weekend. Everywhere we tried said we’d have to wait til Monday or take baby to the ER, neither of which we wanted to do. Enter Sarah. She was professional, prepared, efficient and patient. She gave us successful strategies to use and put us on a schedule to get baby healthy and back on track.

    Amanda R.
  • I started referring my Mothers who were having struggles with breastfeeding to Sarah and they all returned with rave reviews and with newborns who were now successful at Breastfeeding. I continued to refer to Sarah afterward and was never disappointed! Sarah has unlimited patience, as well as excellent technique with lactation advice.

  • After a week of difficult nursing and our newborn infant showing signs of failure to thrive, we were emotionally spent and desperate for answers. We had seen our general pediatrician and had a visit with the hospital lactation consultant, but our baby was still struggling and the recommendations and treatment we were given were not helping. Being a family physician myself, I sought out an experienced lactation specialist with a nursing background to help us navigate what was going on.

    My search turned up Sarah. My partner and I called Sarah on Christmas evening, not expecting to get a call back within minutes. After talking with Sarah that night and sending her a video of our infant nursing, she could already see that our son’s tongue tie had not been completely released by the physician several days earlier. We were so impressed and at ease with Sarah, that we decided to have her fly out to our home in Seattle a couple of days later. Sarah spent the day with my partner and showed her some techniques, came up with a plan and repeatedly followed up to see how things were going.

    She explained that the problems were related to our son’s tongue tie and a milk supply issue related to an anatomical variant that affected the milk ducts. She referred us to a wonderful dentist nearby who specialized in tongue ties and got us in to see him very quickly. Although she explained that the milk supply problem was a barrier, she was supportive of our decision to keep trying and provided guidance and support in the weeks to follow.

    Although we were sad that my partner was unable to breastfeed, we appreciated Sarah’s honesty, professionalism and her expert opinion. Our experience with Sarah could not have been better. Sarah is a positive, kind and fun person to work with. We highly recommend Sarah!
