This bed has really impressed us! It is convenient and lightweight, and the mattress is thick enough for baby. For cons, I most recommend for a child who does not look back again, otherwise your baby may wake up because he has not enough room to roll! Alternatively you can use the Nomad Park as Dodo: my baby there spent hours to play! So I would say that this bed is well suited for children 0-4 months, but it can be used as a park up to 6 months.
