My sister won't let her 18 month old walk around the house. She's only allowed to walk in one room ( on carpeted floor ) with a gate to stop her walking into the rest of the house that has wooden and tiled floors.
My niece started walking 3-4 months ago.
She's in a play pen or high chair whenever she leaves is in rooms without carpet.
I know it's none of my business but I think it's affecting her confidence and abilities too.
