Just an AMAZING update!!!!!

Today I tried your guys' suggestions and I am the happiest lady in the whole wide world!!
Right now I am taking a few moments for myself as ALL 3 kids are sleeping and my 5 year old is quietly playing on the deck!! The 2 & 4 year old went to sleep at 1:15, and my 15 month old went to bed at 1:40 (Still working on moving his naps back as you guys recommended on a different post - so far so good. Has moved from a 10:30 nap to a 10:00 nap and a 2:30 nap to a 1:30 nap which I'm quite surprised how easy it was to do) so he sleeps at the same time as everyone else. I just got the 4 year old to lay down on the couch with a blanket and moved the 5 year old, my son, and myself to the kitchen/dining room and after a bit of tears he passed right out.

I am actually quite excited to see how his demeanor is at 4.
THANK YOU! THANK YOU! THANK YOU!!
