2yr old kicking door at bedtime

Lib

It doesnt matter whether the door is open or shut my 2yr old son will continuously kick the door after we put him to bed. We do a consistentbedtime routine of wash, teeth, story, snuggles and we stroke his head to drift off. But as soon as he notices we are not there or we lesve the room after ssying nighty night he stays by the door kicking it. Not crying or anything, he starts that part when we ignore for a while.... any advice to stop this? Theres 8 of us that live here and nobody wsnts him banging on the door at 7/8pm at night. +
