The size of your baby's stomach: photos

Medically reviewed by Dwight Lindo, Retired consultant paediatrician and neonatologistWritten by Megan RiveLearning about the size of your baby's stomach can help you understand how much and how often your baby needs to feed. You may be surprised by how small his stomach actually is! Approved by the BabyCenter Australia Medical Advisory Board. Photos: Thinkstock

Day one

When your baby is first born, his stomach is no bigger than a hazelnut. Because of its small size, your baby will need to feed often to keep himself feeling full.References: Silverman 1961, Wang et al 1994

Day two

By the second day, your baby's stomach will be about the size of a cherry. Your baby will be able to take in a little more milk with each feed, but he will still need to feed every 90 minutes to two hours.Reference: Beststart 2009

Days three to four

Three days after your baby was born, his stomach will have grown to about the size of a walnut. It's grown a lot from the day he was born!Reference: Beststart 2009

Days five to six

Towards the end of your baby's first week, his stomach will have grown to the size of an apricot. Your baby should be putting on some weight now and be producing around six wet nappies a day.Reference: Beststart 2009

Seven days to two weeks

The expansion of your baby's stomach will have slowed a little now. But by the time your baby is two weeks old, his stomach will be roughly the size of a large hen's egg.Reference: Beststart 2009Advertisement | page continues below

Adult

Your baby's stomach will continue to grow until he becomes an adult. Once he is fully grown, his stomach will be about the size of a grapefruit.Reference: Silverman 1961Was this article helpful?
