OK this is not cheap and maybe seems like an unjustifiable expense alongside all the other things you have to buy in those first months, but this is a wonderful product, worth every penny, as far as we are concerned. Our daughter is not a big fan of sleep and we have to keep her room at home super-dark and quiet to stop her waking up in the hope of someone to play with. As we live overseas from both sets of grandparents, we have to travel a lot and the stress of arriving to find that we need to put her to sleep in a bedroom brighter than Christmas, melts away as we wrap her travel cot in this blackout. More sleep for baby = more sleep for us = happier travelling for all. Once fully closed the blackout also stops her seeing us moving around, so we can easily share a room without too much risk of disturbing her. We absolutely recommend it if you have to travel often and your little one is disrupted by light levels.
