Insomnia you experience during your pregnancy could be due to several uncomfortable issues. This is when your hormones are all over the place, and you’re physically uncomfortable with the baby growing in size, making for an uncomfortable sleeping position.  But this doesn’t last forever and goes away when you deliver the baby. Your hormones start going back to normal, and you’re able to get tired and go back to sleeping 7 to 8 hours during the night. Only now the newborn needs care and attention, so you’ll have to wake up every few hours to tend to their needs.
