Hot Hugs ($30) from Aroma Home are high quality plush animals with a removable pouch in their tummies. Throw the pouch in the microwave for a minute and slip it back in and the animal stays warm for a long time. They are scented with calming lavender and chamomile essential oils, but the scent is soft and delicate.
This is a darling toy for bedtime and my 3-year-old son is very attached to their cute, soft lion. They offer a whole menagerie including a cat, duck, cow, elephant, dog, pig, lamb, monkey and giraffe.
