Are Jolly Jumpers Safe for Babies?
Addressing Questions About Hip Dysplasia and Developmental Milestones
By the Jolly Jumper® Team | jollyjumper.com
At Jolly Jumper, safety is not a marketing statement — it is the foundation on which we have operated for over 75 years.
We welcome questions about our products and take them seriously. Recently, questions have circulated online about infant jumpers, hip dysplasia, and developmental milestones — sometimes referencing Jolly Jumper® by name. This article addresses those questions directly, transparently and with the full weight of the available evidence.
The answer, clearly stated: Jolly Jumper® products have never been linked — in any clinical study, complaint, or confirmed case — to hip dysplasia or developmental delay. Here is what the evidence actually says.
A 75+ Year Safety Record
Jolly Jumper® doorway and stand jumpers have been designed, manufactured, and sold since 1948. In that time, an estimated 10 million babies have used our products. In all of those years and across all of those babies, not a single confirmed case — and not a single substantiated complaint — has ever linked a Jolly Jumper® product to hip dysplasia or a developmental delay.
That record is one we are proud of, and one we actively work to maintain. Jolly Jumper® products are regularly tested against CPSIA (U.S.), CPSA (Canada), and EN (European) safety standards — ensuring that every product we bring to market meets or exceeds the rigorous requirements of the jurisdictions where parents rely on us.
What Actually Causes Hip Dysplasia?
Developmental Dysplasia of the Hip (DDH) is a well-studied condition. Understanding its actual causes is essential context for evaluating claims about any baby product.
The evidence-backed, peer-reviewed causes of DDH are:
- Ligament laxity at birth — the most common cause, typically due to hormones that relax ligaments during childbirth
- Female sex — girls are approximately 4–8x more likely to develop DDH due to greater hormonal ligament laxity
- Breech positioning — one of the most consistently identified risk factors, as abnormal fetal position stresses the developing hip joint
- Genetics and family history — multiple genes have been implicated; risk increases significantly with a family history of DDH
- In-utero restriction — conditions that limit fetal movement, including low amniotic fluid, large birth size, and multiple pregnancies
- Improper swaddling — the strongest modifiable post-natal risk factor; wrapping legs straight and tightly together is strongly associated with DDH across multiple populations
What Research Is Available
No peer-reviewed clinical study — of any jumper product, let alone Jolly Jumper® specifically — has established a causal link to DDH. Where concern exists in professional commentary, it is theoretical and has not been confirmed by controlled research.
The majority of the research has been based on seated infant walkers — the wheeled devices babies sit inside. These are categorically different products, and the safety concerns and regulatory actions associated with walkers — including their ban in Canada and several other countries due to stair-related injury risks — apply to walkers specifically. They do not extend to jumpers, and the two should not be confused with one another.
Not All Jumpers Are the Same
"Infant jumpers" is a broad product category, and products within it vary considerably in design, seat type, hip positioning, and movement mechanics. Where professional opinion on jumper safety does exist, it tends to reference specific sling-style or bungee-style configurations. Jolly Jumper® doorway and stand jumpers have distinct design characteristics, and applying generalized concerns uniformly across all jumper products is not based in fact.
A Relevant Precedent: Baby Carriers and Hip Dysplasia
A similar safety question was once raised about baby carriers and their potential effect on hip development. That question was investigated by credible, independent bodies. Their findings are directly relevant here:
International Hip Dysplasia Institute (IHDI) — Official Position
The IHDI, in consultation with product safety development teams, confirmed based on the best available evidence that no baby carrier can cause or prevent hip dysplasia. The IHDI further affirms that products allowing unrestricted motion do not cause hip dysplasia.
Jolly Jumper® products allow babies to move freely within their natural range of motion. The IHDI's principle — that unrestricted movement does not cause DDH — is consistent with what the evidence shows about our products.
Trusted by Parents. Loved by Babies. For Over 75 Years.
The families who choose Jolly Jumper® deserve honest answers, not reassuring ones. We are confident in our products because the evidence supports that confidence — backed by 75+ years of safe use, rigorous ongoing testing, and a track record that speaks for itself. We will always be transparent about what the science says, and we will always hold ourselves to the standards that parents expect of a brand they have trusted across generations.
Our Recommendation
We encourage parents to incorporate a variety of activities into their baby's daily routine. Use Jolly Jumper® products in moderation as part of a varied daily routine that includes plenty of supervised tummy time and free floor movement. Our products are designed to be a joyful, engaging part of your baby's day — not a replacement for unrestricted play.
