Putting baby to bed

Emma

As my baby approaches 3 months I’m keen to start a bedtime routine and put baby to bed after his bath. He will sleep in same room as me until 6 months but I want to put him down in the evening and have a couple of hours with him sleeping upstairs with the monitor on. Am I being silly doing this so early? Should I only put him to bed when he’s in his own room at 6 months ? Advice would be appreciated !!
