The Best Baby Formula of 2023, According to Reviewers

Kirkland Signature ProCare Dual HMO Infant Formula ($48 for a two-pack)

Leave it to Costco to provide the cost-effective formula we need. One parent who spoke to POPSUGAR — Chad, a dad of three — says Costco's Kirkland-brand formula is his go-to pick: "It's cost effective and until the recent formula shortage, was always readily available." The only downside is you need to be a Costco member to buy it.
