Didn't we call them playpens? I can remember mine from when I was a toddler - I may only remember my little sister being actually in it.
I have tentatively offered a travel cot to my DiL for trips to the loo, dustbins etc, especially as the little one is just starting to move around, but I don't think she's too keen.
Feeling uneasy with tradespeople in the house.
Mysterious hole - help please!
