Play pen or no play pen?!

Li

Ive recently read about play pens being bad for baby and wanted some other opinions!

I use mine to stop my little boy hurting himself as he’s walking already at 9 months and was forever trying to get to our fireplace etc and he’d get upset at me dragging him away all the time from all the dangerous bits and bobs that couldn’t be safely ‘baby proofed’

Its quite big and I saw it as a safe place for him to explore and play. I’m always in there with him playing and hardly ever leave him alone in there but is it bad to have him in there for longer periods even if I’m with him?!

I also walk him round our house during the day so he can explore....

Thanks!
