Breastfeeding, Formula or Both: How to Make Your Decision
Feeding is the decision new parents get the most unsolicited advice about, and often the least support to think it through.
This article is deliberately neutral. It does not rank methods, because the right choice depends on your health, your baby, your situation and your clinician's advice — not on a listicle.
Quick answer
How do I decide how to feed my baby?
Decide with your own healthcare team, using what is known about your health and your baby's needs. Whatever you choose, the practical job is the same: follow a feeding plan, record what actually happens, and monitor output and weight [5] [6]. Published guidance in our research gives frequency and output benchmarks for breastfed newborns; benchmarks for other methods were not covered and must come from your clinician.
Key takeaways
- This is a decision to make with your healthcare team, not from an article.
- Feed plans, records, output and weight matter whichever method you use [5] [6].
- CDC frequency and output benchmarks in our research are given for breastfed newborns [5] [6].
- Mixing methods is common and is not a failure state.
- Nothing here is right or wrong for your family.
Start from a neutral place
People feed their babies in a wide range of ways, and all of them are ways people love their babies. Method choice is not a measure of care.
Our research does not contain the clinical detail needed to compare methods — volumes, preparation, storage, or method-specific output benchmarks. We are not going to fill that gap from memory and risk getting it wrong, so ask your own clinician for volumes and preparation.
What is the same whichever method you choose
The practical work does not change very much, and it is the part worth being clear about [5] [6].
Whichever method you use
- Follow the feeding plan your clinician gave you
- Record when feeds start
- Note anything that makes feeding difficult
- Track wet and dirty diapers
- Attend weight checks and bring questions
Using published figures carefully
CDC guidance says breastfed newborns commonly feed 8–12 times in 24 hours, and identifies fewer than six wet diapers a day by five days old as a possible sign of insufficient intake in a breastfed baby [5] [6].
Questions to take to your appointment
- What feeding plan fits my situation?
- How often should my baby feed with this plan?
- What output should I expect?
- What would make you want to change the plan?
- How do I contact you out of hours if feeding worries me?
When to call your doctor or midwife
If feeding or output concerns arise, contact your healthcare team [6] — whichever method you are using.
