Travel with Children
The good news is that Lima is full of families and locals are very welcoming toward children. Streets have a fair amount of chaos; if your family isn't used to navigating a busy city, you might find refuge in LarcoMar mall. Look for ludotecas (educational centers) that can provide indoor fun for a few hours. Kids can enjoy Parque del Amor, Circuito Mágico del Agua, chocolate-making workshops at Choco Museo outlets and beach time just outside the city.
Strollers can be more of a frustration than a help, unless you are staying fairly close to Miraflores' cliff-top trails, which can be excellent for strolling.
