how old is babe? Can he crawl, if not, folded blanket in a drawer. My mum always puts the babies in this when they visit. I think it is sweet and old fashioned but always worry she will absentmindedly shut the drawer with them in.
He's 9 months old and enormous - 31.5 inches so I don't think he'll be OK in a drawer (tempting as that is sometimes!).
My mum has a travel cot which we'll be able to borrow, but he's never slept well in it when we've visited. He's used to a nice thick mattress so I guess the inch of floppy foam doesn't quite cut it! And he hates the mesh sides as well.
