Take magnesium supplements and try some activity before bed to get your body tired. White noise also helps to drown out sounds and sometimes even your own thoughts.
This breathing technique works for me sometimes - I don't make the whoosh sound as it would wake my husband! And also works if I breathe out through my nose too.. worth a shot! Close your mouth and quietly inhale through your nose to a mental count of four. Hold your breath for a count of seven. Exhale through your mouth, making a whoosh sound for a count of eight. Repeat the process three more times for a total of four breath cycles.
I’ve been finding it super difficult to switch off and sleep recently but I’m so so tired and all I want to do is sleep 😭 and then know I’ve got to be up in the morning with little one. So difficult! Plus I feel like I’m always sleeping with one eye open 😭
