Wing Yan has helped us achieve our sleep goals for our daughter and we are thrilled! Traveling is no longer a chore, as our daughter can now self settle and sleep through the night even when she's away from the familiarity of her own home. We are so grateful for Wing Yan's help as it has changed our life! My husband and I had an extremely positive experience with Wing Yan at Precious Sleep. She is professional, empathetic, confident, patient, and is great at what she does. We could sense her dedication to her job, and would highly recommend her services to all sleep deprived mums and dads!
