Review on Pehr Alphabet Sleep Bag, 0-9 M by Mike Stevenson

This worked really well for us and we never had an issue. It hugely helped us transition our son from swaddles to sleeping more independently in his crib. I think this is definitely for older babies who are a little bigger. We tried to use it when he was small and he was swimming in it! The only thing I worry about in this is overheating, but we have never had an issue and keep the temperature in his room consistent.
