Hi all my LO is 23mo and is generally a good sleeper. However my husband gets up to go to work at 5am and even just slight movement around the house at that time wakes her. Recently when it was really hot I put a fan in her room and she didn’t wake at 5am when my husband got up. I don’t know if it was a coincidence or whether the fan masked the noise? I don’t know if it’s too late to introduce white noise to help drown out the early morning sounds or whether it’s a habit I don’t want to start at her age? I should point out She’s not a naturally early riser and is a complete misery when she wakes so early! She’s very tired! Any advice? Can the noise actually be worse and distracting if the toddler isn’t used to it?
