Does Ica have a separate nursing room? Or is it just the baby care room? Baby is howling so I ducked into the baby care room to nurse. But there is no lock. So confused.

Nope it doesn't. There are two, one on level 2 and another on 3. They are pretty basic and the changing and nursing areas are joined and right next to each other. Usually mommies would use their prams to prop against the door or get someone to stand outside to make sure no walks in by accident. Best to use a nursing cover if you need to nurse.
