Sleep help

My lo does not need soothing to go to sleep, from 6 months he has been great at getting to sleep in his own room. For the last few months we have struggled to get him to sleep through, he now wakes multiple times a night and will now only settle back to sleep in our bed. He just turned 18 months. He wakes around 6/7 am, he will then either have a morning nap for around an hour/hour half or one in the afternoon for the same time. We put him back to sleep after a bath around 7:30/8 Open to suggestions 😆
