4 month night feeding

Janan

My boy sleeps from 7/8 pm to 6/7 am.His is EBF.Last feed normally before bed .I used to dream feed him around 11 pm.But for the last 2 days I skipped it and he was just sleeping as usual.Can I leave him to sleep without feeding for 11/12 hours?

He sucks his thumb to self soothing.I am worried he is skipping feeds due to this.Any one has same experience?
