Not just advice—evidence, translated.

Breastfeeding advice can be noisy and contradictory. Lactology filters the research and translates it into clear, actionable guidance—without the guilt, fear, or fluff. We also openly acknowledge that evidence evolves (because it does), and your care should evolve with it.

Practical plans you can follow at home

Evidence-backed support (with sources when you want to go deeper)

Inclusive care that supports all feeding journeys

A calm, professional space for overwhelmed parents

Meet your Lactologist

Hi, I’m Courtney Slegers.

Lactation & Breastfeeding Counsellor

I founded Lactology because mothers deserve structured, evidence-based breastfeeding support—and they deserve it now, not years after clinical practice catches up. My work bridges clinical care, education, and research so families can feel informed, supported, and confident through every feeding stage.

  • “I am a mother of 3 children. I struggled with breastfeeding with my first 2  babies. I managed to breastfeed my 3rd child for at least 12 months. Courtney has been such a huge support, very kind, understanding and is a wealth of knowledge that has blessed my life in more ways than one. I cannot thank her enough for the support over the years!”

  • “I had breastfed my previous three children with no problems. At 43 I fell pregnant again after many years and struggled to feed my 4th son. Courtney supported me through it all, offering advice and giving me many tools. Before I met Courtney I was told my supply was too low. My son is currently 19 months old and we are still breastfeeding thanks to Courtney. I highly recommend her not only for her professionalism but the way she loves and supports you"

    —Nicole

  • “Courtney has what I believe every parent should have on their side; a strong scientific understanding of breast feeding physiology and an incredibly caring nature. She consistently makes something that feels so difficult at times achievable. After many years of study, research and application of her methods, she has created a diverse approach in her practice to troubleshoot breastfeeding concerns. Not only is she helpful for breastmilk production, latching and overcoming what are thought to be physiological barriers, she focuses on the breastfeeding triad and a scientific approach to the support needed during this crucial time.”

  • “Nothing could have prepared me for the immense challenge of breastfeeding my beautiful twin daughters. We had to deal with a premature delivery, low birth weights, no suck reflex, giant engorged breasts that my teeny babies couldn't even get their mouths wide enough open for until they were a few week old, as well as low breast milk supply.  I felt defeated and like I was failing.  And then came Courtney - a truely empathetic professional who provided me so much support. Her compassion was unmatched while offering science based approaches and solutons. My journey changed completely. I am so so glad that I took a chance and asked for help. Thank you Courtney!”

    —Samantha

  • “Courtney has dedicated herself to the study of lactology, and her wealth of knowledge is an asset to every mother. Courtney's kindness and dedication to her patients shines through in every interaction. As a mum herself, Courtney understands the challenges of motherhood first hand, and is able to approach each case with empathy and compassion. I have no hesitation in recommending Courtney to anyone who needs support on their breastfeeding journey.”

    —Joanne

  • “Courtney was absolutely amazing after I had my fourth baby. I had previously expressed/bottle fed with my first three babies, and when I had my fourth, I was scared to breastfeed but always wanted to. The midwives said “oh this is your fourth baby - you’ve got it covered” and didn’t help me at all. I left the hospital defeated and decided to express again as it was what I knew. Four weeks in my supply felt like it was dropping and I rang Courtney in tears, and she came straight over to my house and took the time to help me figure out breastfeeding. She showed me different holds and techniques to get her to feed/latch and made me feel so comfortable and heard. I ended up feeding my daughter for almost 4 years. I had my fifth baby last year and once again, she was invaluable - checking in to see how I was going, making sure my latch/feeding and supply was okay. Without Courtney I don’t feel like I would have been able to breastfeed number 4 and 5. I’ll be forever grateful for her exceptional support and care postpartum. 100% recommend Courtney to look after you and your babies.”
