My son is now 15 months old, he actually slept pretty great as a baby, but when he got older not so much. Whether it was molars or just a phase it was awful, he woke up very two hours, I was finally at my wits end and was trying everything. I noticed making his bed time a bit later helped. Wahoo! He was sleeping a bit better. The next thing I tried was leaving a little light on and bam he slept even better. He's been sleeping through the night now every once in a while he may wake up but usually goes right back to sleep. It worked for me who knows it might work for you. Good luck and may sleep become your friend once again!
