I have 9 month old twins (6.5 months corrected) and they have recently started rolling and doing this bum shuffle thing when lying on their backs. I don’t think it’ll be too long before they’re on the move! Can anyone recommend a sturdy and large play pen that is good for twins? As I feel just baby proofing won’t be enough lol. Good value if possible but I am willing to pay up to £200 for a good one
