"A Quest for Toddlers" is not unlocked until level 12. Until you unlock and complete the quest, your infants will not be allowed to age up.

A tip: To level up quickly and earn extra cash, plant onions (my personal favorite plant, as when your sims are inspired they collect 1,200 simoleons.) It'll give you extra cash, and bring your levels up quickly.
