I have 3kids due with #4 my oldest is good at knowing bedtime.my youngest sleeps thru the night its my 17month old who DOESNT sleep thru the night never has.

He will cry n scream until he gets a bottle

(3-4x a night)i have to change him 2-3x or he will be all wet by 7am when he wakes up he only has one nap a day no more then 2hrs

Ideally id like them all asleep by 8pm but i need help or ideas/tips on ways to help my 17mo old sleep thru the night

Like i said he never has its always been an issue but i am due w. #4 later this year so i want everyone on the same schedule
