normally, if breastfeeding, di na siguro. however, you will need to leave your baby from time to time, like going to the cr/kitchen --- and once the baby rolls over, prone na yan, na mahulog sa bed, kahit na palibutan mo ng unan yung bed. the safest "containment" unit, is a crib/playpen. buy a big one, that will serve as a play area na rin, para dual purpose. if it's just a bed/crib, and you would want to co-sleep, di na necessary yung crib-bed.
