They immediately sent me details of two night nannies, and the one I decided on has been looking after our baby son overnight several nights a week for the past 3 months. When she first came to us, our son was only sleeping for 2 hours at a time, waking up angry, refusing to go back to sleep, and refusing to feed. He was tired and grumpy during the day, and cried every time we tried to put him down. She worked with us to establish a routine for him, along with good sleep associations, and within a week, he was sleeping for 5 hour stretches overnight! He is now 6 months and is sleeping through the night. She really went above and beyond, often what's apping me to ask me how the nights went when she wasn't there and giving useful advice about his day time naps and feeding schedule.She is always punctual and professional, not to mention warm and personable. She immediately made me feel at ease, and my son loves her. I could not recommend my night nanny more highly, and have already made her promise to come back should I have more children. .
