It depends..
Hi, it depends on where in Dr you are moving, and also the age of the kids..
In Puerto Plata where I live you can find most of the things needed for kids of all ages. Like clothes, toys, beds/chairs/ sulkies etc etc.
Best for that is Messon, Casa Nelson and Jimenez.
Many people with small kids alos do their shopping in Santiago.
Some close friends of mine have a 3 year old, and another friend a 5 year old, and those kids miss nothing I?d say.
In Puerto Plata the most popular preschool is the Montessori school in TorreAlta, but there are for sure others around too. The Montessori school have an English tutor as well employeed.
