Anyway, she had these custom-made in Nueva Ecija, I think. They can accommodate babies up to three years and are supported by low, wooden structures. It's actually a very wise design, for in the event a child falls off the crib, he wouldn't have that far to fall from. Same reason why some setup their hammocks right over the family bed: sleeping parents can swing it while half-asleep, mommies need not get up to get to a hungry baby, and babies won't fall from a high place in case they get too wriggly in the hammock (usually made from a blanket).
I've told hubs I want one like this for our next child. Hopefully, we'd have the space for it (maybe some plastic chests can go).
Yakee's didn't really work for us eh.
