Allergens & Warnings Keep away from any source of flame. Ninjamas nighttime underwear, like almost any article of clothing, will burn if exposed to flame. To avoid risk of choking on plastic, padding, or other materials, do not allow your child to tear the pant, or handle any loose pieces of the pant. Discard any torn or unsealed pant, or any loose pieces of the pant. To avoid suffocation, keep all plastic bags away from babies and children. If you notice gel-like material on your child's skin, don't be alarmed. This comes from the nighttime underwear padding and can be easily removed by wiping your child's skin with a soft, dry cloth

Fit well, design is cute and holds alot.

My girl is a little big for her age and still uses a "pull up" at night. We've tried so many other brands and none fit or hold as well as these. While the design isn't character related, she still loves the unicorns and flowers. She is about 50lbs and wears a girls size 6 in clothes and 8 in panties. The Small/Medium fit perfectly. They don't leave lines from being too tight and hold liquid very well. The Ninjamas are also soft and comfy. She has some sensory issues and these do not bother her at all.

strong scent

haven't used these yet so can't comment on how well or not well they work but i can tell you they have a very strong fragrance, and i wouldn't recommend if your child has sensitive skin. will not be purchasing again.
