Voting rules: Choose the toddler age you think is the most difficult!
This is a community-based ranking of the most difficult toddler age. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or toddler age is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each toddler age once every 24 hours. The rank of each toddler age is then calculated from the weighted sum of all up and down votes.
