My 11 month old son gets what I call cry hiccupps a lot when he sleeps.  He breathes like a child does after he has been crying really hard.  He sleeps through this and it can last for hours.  Is this normal for children?  My other son never did this.
Cry hiccups. Not heard of . Could be sobbing spasms.are they sound like a persistent musical sound? What we call as "strider"? Does it get aggravated by respiratory infections? If so, then you have to see ENT doctor otherwise you can ignore them.
