I refuse to sleep in the same bed as my child simply because my baby boy can take up some major space, making my sleep uncomfortable.
At first his crib was in my room and while he was still breast feeding, I would lay on the bed and feed him if I was tried and sometimes I would fall asleep and as he got bigger he would drink from a bottle I would leave him in his crib but he would always wake up and want me, my doctor told me to ignore it, that Jaxon (my son) needed to learn that night time is sleep time and mommy will not play with you until the sun comes up. After a week of this (maybe less) he was learning, not to long after that I moved out of his room and he got a toddler bed, which was easier to get out of, thank god he did not know how to open doors, and me being out of the room was different and scary to him, so every night I would play in his room with him and read stories and leave his drink with him and lay him in bed tuck him in give him a kiss and say goodnight I’ll see you in the morning, the moment I shut the door he started to cry, and some nights it took an hour, he would get up and throw his pillow on the floor and lay on it and cover himself with his blanket, I would return to his room when I knew he was passed out, and put him back in his bed, after a week he was use to it and now he is two and night time is easy for me, and sometimes he’ll still cry but only for a minute or two.
If you can’t stand hearing him cry go to the other end of the house and wait it out.
I hope this example helped
