My little one has just recently started sleeping through the night. Yay! But now my sleep is so messed up. I sleep with a monitor so I hear him wake in the morning or if he needs something in the middle of the night (his room is on the other side of the house) but I often think I hear him crying out when he's not and I get up early even though I'm still sleepy. I was a great sleeper once and now I am so tired even though I get 7 hours sleep at night. I don't think I'm getting enough deep sleep. I took melatonin and now have taken Ambien for a few nights without any difference other than falling asleep quicker. Any suggestions?
