Sex: All

Target Recruitment: 10

Inclusion Criteria

Informed consent by the parent or legal guardian.
Male or female infant 4 to 12 months corrected gestational age at screening.
Weight at least 5 kilogram (kg) and weight-for-length Z-score greater than -2 at screening and baseline.
Short bowel syndrome with dependence on parenteral support to provide at least 50% of fluid or caloric needs.
Stable PN requirements for at least 1 month prior to screening, defined as a less than or equal to (<=) 10% change in the weight-normalized PN total fluid and caloric intake, despite attempts to wean PN, not withstanding transient instability for events such as sepsis or interruption of central venous access.
Parent or legal guardian understands and is willing and able to fully adhere to study requirements as defined in this protocol.

Exclusion Criteria

Previous treatment with teduglutide.
Intestinal malabsorption due to a genetic condition, such as cystic fibrosis, microvillus inclusion disease, etc.

Dysmotility is defined as severe if it is expected to limit the advancement of enteral feeding.
Inability to advance oral or enteral feeding due to lack of access to the gut, such as oral aversion in the absence of a feeding tube.

Biliary obstruction, stenosis, or malformation.
Clinically significant pancreatic disease.

1. International normalized ratio (INR) greater than (>) 1.5 not corrected with PN vitamin K
2. Platelet count <100×10^3/ microliter (mcL) due to portal hypertension
3. Presence of clinically significant gastric or esophageal varices
4. Documented cirrhosis
Persistent cholestasis defined as conjugated bilirubin >4 milligram per deciliter (mg/dL) (>68 micromoles per liter [mcmol/L]) over a 2 week period.

Concurrent treatment with glucagon-like peptide-1 (GLP-1); glucagon-like peptide-2 (GLP-2); insulin-like growth factor-1 (IGF-1); growth hormone, somatostatin, or analogs of these hormones; or glutamine.
Participation in a clinical study using an experimental drug within 3 months or 5.5 half-lives of the experimental drug, whichever is longer.
Known or suspected intolerance or hypersensitivity to the investigational product, closely-related compounds, or any of the stated ingredients.
Any condition, disease, illness, or circumstance that, in the investigator's opinion, puts the participant at any undue risk, prevents completion of the study, or interferes with analysis of the study results.
