Tips for Bedwetting
  • Ensure your child drinks 6-8 cups of liquid based drinks per day
  • School aged children (5 and over) should empty their bladders 4-7 times per day. Regular filling up and emptying of the bladder strengthens the bladder muscles
  • Monitor how often your child empties their bowels - did you know that constipation is the #1 cause of bedwetting?
  • Encourage your child to go for a wee before bed and upon waking
  • Stop drinking liquids 1 hour before bedtime
  • If your child is 5 years and over and in the UK - you can visit your GP for support
  • Join over 80k happy families
  • If your child still experiences daytime toileting issues the focus on fixing these before tackling nighttime dryness
  • Please don't worry!

Sleeping Bag Liner FAQS

What happens if there’s an accident overnight?

If the liner becomes wet, carefully roll or fold it inward from the top when removing it from the sleeping bag. This prevents liquid from leaking out through the mesh foot panel and keeps the sleeping bag dry.

Is it washable?

Simply pop in the washing machine at a maximum temperature of 40°C on a normal cycle. We don't recommend using fabric conditioner or bleach as this may degrade the waterproof layer but other washing detergent is ok to use.

You can also hand wash the sleeping bag liner - if you are away from home such as camping, you may not have access to a washing machine, so hand washing is absolutely fine!

How quickly does it dry?

The liner dries quickly thanks to its lightweight, breathable layers. For fastest results, line dry or use a gentle tumble dry setting.

Is it crinkly or noisy like other waterproof products?

Not at all! The liner is made from silent, soft cotton jersey with a waterproof layer that doesn't rustle – so your child can sleep soundly without distractions.

How does the sleeping bag liner work?

Our liner has three layers: a soft cotton jersey top layer for comfort, a waterproof middle layer to prevent leaks, and a breathable mesh foot to promote airflow. It discreetly fits inside your child’s sleeping bag to protect it from accidents.

Can I use it at home too, or just for sleepovers and camping?

You can absolutely use it at home! It’s great for beds, air beds, or even sleepovers at a friend’s house or in a hotel - anywhere you want extra peace of mind.

Excellent quality product

Good quality. Perfect for use with a sleeping bag and could also be used for sleepovers. Very soft material. Good value for money. Didn’t see anything similar to this product.

Great protection

I got this waterproof sleeping bag liner for a family camping trip, and it worked really well. It fits neatly inside the sleeping bag and feels comfortable to sleep on. I love that it’s breathable and doesn’t make crinkly noises. The mesh panel at the bottom helps with airflow, but I did notice that if my child had a big accident in the night, liquid could seep through the mesh if I wasn’t careful in removing it in the morning. I’d definitely recommend it for sleepovers and camping trips!

Super convenient for sleep-overs

Our son went on a sleep over at his friends and had an accident during the night. The liner kept the sleeping bag perfectly dry - very impressed. He also found it very comfortable to sleep in. Will be buying another for longer camping trips too. Highly recommend.
