Just that really.
DS is 5.5 months and starting to think about crawling. PILs are from America (but live here now) and keep reminding me to get a playpen as apparently I need to start putting him in it before he becomes mobile so he gets used to it. But I don't think any of my friends or family in the UK has used one of these, they've all just babyproofed as much as possible and kept an eye on what the baby's up to. And the more I look at them, the more they look like little cages.
Is this a cultural/generational thing, and people here don't tend to use them, or am I being precious/naive?
