Changing a 15 month old from a crib to a bed?

My 15-month old son has recently had many mid-night waking . We have tried many methods of putting him back to sleep in his own bed but ultimate this is resulting in him joining us in our bed and lots of crappy sleep for us. We let him sleep in our bed for comfort due to illness or teething discomforts but don’t want this habit to take out as a norm. He is also VERY physically mature for his age and extremely mobile. My partner and I are toying with the idea of moving him to a big boy bed. We have that parent’s instinct that he is ready. On the other hand we don’t want to prematurely move him and cause MORE sleepless nights. Of all the reading I have done on the internet, most people are changing at 2 years or after, and occasionally at 18 months. I would love to hear some feedback from people that made this transition earlier than 18 months, how it went, tips, bedtime routines, anything!
