Getting my 14month old to sleep in room all night

Every sense i bought my baby home my 14th month old will not sleep all night in his room. I Have not been able to really get him to stay in his room. We will be starting a routine today to try to get him to stay in his room without his cup. I had the hardest time breaking my older son from needed a drink at night. It is very hard on me and harder on my husband because we get no sleep. My husband has to go to work so he really needs some sleep. This is what i plan on doing.

1. We will go to his bed and read a story and drink our milk cup.

2. then he will lay in his bed and i will sit on the floor next to it.

3. when he does fall to sleep we will tuck him in and go to bed.

4. when he wakes up i will go to his room tuck him back in and rub his back maybe even read another story or listen to a lullaby.

5. we will do this every time he gets up and see how he does.

I will keep updating you every day and give you advice . Please give me your advice too.
