My poor son (currently 3 1/2 months) won't sleep. I can't help but feel so jealous for all the posts about how great their babies sleep. My son will only nap a half hour at a time and it seems constant from the time he wakes up he still tired and has to go back down. At night he will only sleep 1-2 hours at a time. I started sleep training last night and it was horrible. Every hour I had to listen to him cry and with no avail. Please share your stories or any advice that got you through this. I feel all alone in this journey. My husband works nights, so it's even more difficult.
