Thanks for your reply!
Maybe I should have opened a new topic, the title can be a bit misleading because he's almost 8mo now!
As you recommended we're trying 3h15 A time, although the result varies, sometimes he stays awake longer. But in general he's going to sleep much more easily, now we just put our hand on his back and shhh (both for naps and BT). Some days he fights more than others, but he's not OT at night.
At his first night waking, I try to soothe him with water or my hand, and if everything fails I feed him and that always works. I don't know if it's hunger or learnt hunger, because sometimes he eats very little and sometimes he eats more.
Here are his last days:
