A note before we start: I travel with a travel cot every single trip, and honestly, some nights I don’t even set it up. It’s there “just in case.” Bending down every time Nayeli wakes to bring her into my bed is more than I want to deal with at 3am, so more often than not, we end up co-sleeping instead. This guide covers what’s actually safe, and the honest reasons a travel cot sometimes sits unused even when you’ve packed it.

Search this question and you’ll find a lot of conflicting opinions, forums full of parents worried it’s somehow “less safe” than a real cot, and product pages that avoid a straight answer entirely. Here’s what’s actually true, plus the honest, unglamorous part nobody quite says out loud: sometimes the travel cot just doesn’t get used, and that’s fine too.
What the safety guidance actually says
The Lullaby Trust, the UK’s leading authority on safer infant sleep, addresses this directly: travel cot mattresses are thinner than a standard cot mattress, but that thinness alone doesn’t make them unsafe for long-term use.
- The mattress is firm and flat, with no sagging, rips, or tears
- It meets British Safety Standards (or your country’s equivalent certification)
- You’re using the mattress that came with the travel cot, not a substitute, unless the manufacturer specifically confirms a replacement fits properly
- There’s no gap between the mattress edges and the cot’s mesh sides, gaps are where the real risk lives, not the mattress thickness itself
One thing worth knowing: a travel cot sits lower and closer to the floor than a standard cot, which can mean a slightly cooler sleep surface in a cold room. This isn’t a safety issue on its own, just something to factor into how you dress baby for sleep, and a reason to keep the cot away from drafts, exterior walls, and cold flooring where you can.
The real question isn’t safety, it’s practicality
Once you know a travel cot is genuinely safe for long-term use, the actual decision comes down to something far less discussed: whether it fits how your nights actually go, not whether the guidance allows it.
This is the part that rarely gets said honestly: a travel cot can be perfectly safe and still not be the thing you reach for every night. For me, the real friction isn’t the cot itself, it’s what happens at 3am when Nayeli wakes and needs me. Getting up, bending down into a lower cot, lifting her out, settling her, then doing it all again an hour later, that’s a lot more disruptive to both of us than her simply being next to me already.
- Some accommodations don’t allow or support safe co-sleeping setups, a firm mattress and a securable bed edge aren’t guaranteed everywhere
- It gives me a genuine option, not an obligation, some nights it gets used, some nights it doesn’t
- Early in the evening, it’s genuinely useful, a safe place to put baby down while unpacking or settling into a new room, even if she ends up in bed with me later
- If safe co-sleeping practices (firm mattress, no alcohol or medication, bed pushed against a wall or barrier) aren’t in place for whatever reason on a given trip, having the cot ready matters
How long can you actually use one
There’s no single universal age limit, it depends on the specific model, your baby’s size, and how mobile they’ve become. A few clear signals matter more than any age on a chart.
- Baby can pull themselves up to standing and reach the top rail, this is usually the clearest practical signal, regardless of the manufacturer’s stated age range
- Your baby’s height or weight approaches the manufacturer’s stated limit, always check the specific model, these vary meaningfully between brands
- Your baby is actively trying to climb out, even if they haven’t succeeded yet
- The mattress shows real wear, sagging, flattened patches, or damage, regardless of your baby’s age or size
Keeping it safe over months of use
If you’re relying on a travel cot for weeks or months at a time, whether you travel a lot or you’re using it at home for space reasons, a bit of regular upkeep keeps it genuinely safe rather than just technically compliant.
- Check the mattress regularly for flattening, sagging, or any tears in the waterproof cover, replace it with the manufacturer’s specific replacement if it wears out, not a generic one
- Inspect the frame and locking mechanisms every so often, repeated folding and unfolding on trips is exactly the kind of use that can loosen joints over time
- Keep it away from radiators, direct sun through windows, and cold exterior walls, the mesh sides and low profile make it more exposed to ambient temperature swings than a solid cot
- Wipe down the mattress cover periodically, especially after travel, hotel and rental accommodation dust and allergens differ from what your baby’s used to at home
- Don’t add extra padding, pillows, or a thicker topper to make it feel cozier, this reintroduces exactly the entrapment risk the firm, flat, well-fitted mattress is designed to avoid
FAQ
Can a baby sleep in a travel cot long term?
Yes, according to The Lullaby Trust, as long as the mattress stays firm, flat, in good condition, and meets safety standards. The mattress being thinner than a standard cot mattress doesn’t make it unsafe on its own.
Can a baby sleep in a travel cot every night?
Yes, it’s designed to be safe for nightly use, not just occasional trips. Whether it actually suits your routine long term is more a question of practicality than safety, some families find it works every night, others use it some nights and not others.
What age can a baby sleep in a travel cot until?
There’s no single universal age, it depends on the specific model’s stated weight and height limits. The clearest practical signal is when your baby can pull themselves up to standing and reach the top rail, that’s usually the point to move to a proper cot or bed.
Can I use a thicker mattress in a travel cot for more comfort?
It’s best avoided unless the manufacturer specifically confirms the replacement fits properly. A mattress that doesn’t match the cot’s exact dimensions can leave a gap along the mesh sides, which is a genuine entrapment risk, more important than any extra comfort it might add.
My baby won’t sleep in the travel cot, what should I do?
It’s common, especially away from home. Keeping familiar sleep cues close, the same sleep sack, white noise, a comfort object, helps more than the cot itself. And if it genuinely isn’t working on a given night, safe co-sleeping is a valid alternative, it doesn’t mean something’s gone wrong.
“A travel cot is safe for the long haul, but safe and practical aren’t always the same thing, and it’s okay to admit that.”
Keep the original mattress, check it regularly, and stop once your baby can pull up to standing. Beyond that, whether it becomes your baby’s actual sleep space every night or just a safety net you pack “just in case,” both are completely fine. Some of our best nights on the road have been the ones where the travel cot stayed folded in the corner, and Nayeli slept right next to me instead.
