Hi all, hoping for soem words of wisdom! LO is sixth months old and has been rolling with gusto for the past couple of weeks. I'm finding now he needs to be under my beady eye now as he obviously cannot be trusted to just lie in one place anymore. He has a big playmat that's about the size of hearth rug so can usually roll about on that, but he gets a bit upset when he rolls off, and I find I can;t leave him for fear of him rolling away and hurting himself. So...do I buy a travel cot / playpen / baby prison, or buy a babywalker to plonk him in (he wouldn;t be able to go anywhere in it)? He has a door bouncer which he likes but obviosly I can;t have him bouncing away all day. Think he'd like a jumperoo but they're too expensive for me.
