Little feet get everywhere – I liked the idea of being able to have the different liner weights but my daughter always gets her legs down between the two layers. I thought at first this was because she was too small for the bag but have tried again months later and it still happens. The domes are not strong enough to hold the layers together, popping apart very easily and making room for little legs to get into a tangle. During the night, when she wakes I'm always wondering if it's her legs stuck, or cold feet. Disappointing in a product that otherwise seems really good. Fabric, weight weak domes make it unusable.
