Great, I have two children; a 9 year old boy and a baby 2 months, I have gone for 2 sheep and polar bears. Both worship and not in separate more. I have no pb with microwave, unlike a person who left a comment. The heat is gentle but persistent which is good for my baby because it reminds her body heat and reassuring. So she sleeps better and longer without being ds my arms. The great also adopted and every evening he warms himself in the microwave, no more than 2 minutes and hop! Go to sleep! We can also put it on a radiator (not electric, eh !!!) for those who do not have a microwave or do not like it. It is also used to prop baby on his side because the toy is big enough for that. Not bad also for colic because it keeps warm baby belly (heat ds shorter this case: 1 min 30 eg). I recommend!
