  1. Quick tip for all you parents all out there: My baby never slept well (especially through the night) until I started using the website >>>>SleepBaby .org<<<< - that website has been by far one of the best things I've ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! Sorry, you can't post links here so you'll have to turn it into a normal link. >>SleepBaby .org<< Best of luck to you and your family! :)
