15 month old won't sleep

[otismommy]

About 7 days ago my 15 month old son stopped wanting to go to sleep. We have a nice routine for napping and going to sleep for the night, neither of which have changed. When we lay him in bed now (no matter how tired he is or how close he is to sleep) he perks right up and wants to play. Also he doesn't want us to leave the room, neither of which had been a problem up until a few days ago. As soon as we do he begins to cry and scream. When we've tried pick up put down, he tries to play. It's been taking him about 1 hour on average to get to sleep. At this point I'm incredibly frustrated and don't know what else to do but let him cry, but I just don't feel right about that. It seems like there must be another way. HELP!

Hi
It could be something like molars or a growth spurt that are making him do this.
I wouldn't recommend letting him cry,it only really makes it worse.
you could try PD,which is similar to PU/PD but instead of picking him up,you just lay him
straight back down.I would recommend going out of the room once you have laid him down
and counting to 10,then go back in,lay him down,go out,count to 10,go back in,lay him down
etc and carry on until he stops crying.Stop counting when he stops crying and don't go in
to check on him when it goes quiet.
The first night really is the worse,it took emily 50 minutes,the second night took about 30 minutesish
then after that it was fantastic.
Persevere for at least 7-10 days and keep it consistent.The screaming initially will drive you potty
but I assure you it will get better
