Baby Boum Gimik Fleece Sleeping Bag 1.7 Tog for 0-9 months £7.27 @ Amazon
Baby Boum Gimik Fleece 1.7 Tog Sleeping Bags in lime green are currently on offer at Amazon for 76% off the original price of £29.99.
These look seriously cool, with zips and bits in random places. There are different sizes and colours, but they're more expensive, it's just the 0-9 months in lime green that's reduced.
These have a two way zip mechanism so it can be used as both a sleeping bag and a jumpsuit, which is perfect if your baby turns into a crawler. I must admit, I love things that have more than one function for babies and children, because with the prices of things... well, stretching something's usefulness is great. There are also cuffs in the bottom so toddlers can pop their feet through and toddle about safely in the jumpsuit.
These sleeping bag jumpsuits are machine washable at 30 degrees and can be tumble dried on low heat.
