We would need tips and advice to guide us in a caring way to help him and us.

My 15 month old baby cries a lot, for everything and for nothing... night and day. As he doesn't express himself yet, I'm under the impression that this is his way of asking or trying to make himself understood. We can stay calm and ask him to tell us with words what he wants, he only cries and cries. The whole thing starts to affect our mood, our family atmosphere.
