It's possible that lower prolactin and less oxytocin- that's the hormone responsible for milk release- would cause sleep disruption, because prolactin and oxytocin can make you feel relaxed and affectionate, which can make you sleepy. But there are a lot of other hormones in your body that could be at work! In particular, thryoid imbalances can cause sleep disruptions.
Things to do to cope with insomnia:
- make bed a place where sleep happens- don't read work stuff in bed, don't surf the web in bed, don't watch tv in bed, etc.
- avoid artificial light in the evenings (the more your body is in tune with the natural changes in light levels, the more you'll feel like sleeping when night comes)
- try doing about 10 minutes of deep, slow breathing (if you have a smartphone or tablet, there's a great app called "Breathing Zone" which can be very useful)
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
