Waking up a lot at night

Br

My son will be 6 months next weekend. But recently he has started waking up quite a bit during the night. Luckily he doesn’t cry or anything. He just picks his feet up and slams them back down and talks but idk why he keeps waking up?!? It makes it harder for us to sleep. At least me cuz I’m a light sleeper. Anyone else kid waking up in the night again?
