What are some free things to do with an 18month old? :) it doesn’t have to be in phoenix
Put them in a diaper only and let them have a paint party on a big paper
If your looking for socially you can look into your local library for toddler time things and your local gymnastics place sometimes has toddler open gym usually free or like $5 for like 2 hours and if you contact your local early intervention or head start and ask them and ask them for their monthly magazine or flyer that offers things to do too that are free. Sometimes low income offices have free things listed on their boards for ppl to do w their kids too. Hope that helps.
