Rising daycare bills push millennial parents to widen the gap between children

Kristin Darnell and her husband delayed their second child after realizing that caring for two children in daycare would have required more than $3,000 per month, eventually using IUI to achieve a three-and-a-half-year age gap. A 2026 CDC report indicates that only a minority of mothers in their 30s intend to have another child within two to five years, reflecting concerns over both expense and fertility decline. Experts such as sociology professor Karen Guzzo note that the real cost of childcare often becomes apparent only after a first child arrives, with annual fees ranging from $7,600 to $24,000 per child and potentially surpassing $50,000 for two.

Parents like Angela Donahue report monthly daycare bills of about $5,000, exceeding their mortgage, and cite the financial relief of having only one child in care at a time. Wider age gaps also appear to ease parenting, as older siblings can assist with younger ones and are more communicative, a benefit highlighted by Trish Byron-Wilcox. However, waiting longer can increase reliance on fertility treatments such as IVF, which can cost $15,000-$20,000 per cycle, making the trade-off between savings and medical expenses a central dilemma for many families.
