£110 on amazon. We love ours, it doesn't fit in our crib safely (sides squash so no room for baby to turn head to be sick) so in the crib we rolled towels under the sheet to give the comfort feel for her. Our sleepyhead comes into its own when she ends up in our bed, it enables me to sleep better knowing she is cocooned. If you buy on amazon they can get it to you quickly so unless you have lots of space I would wait.
Loved it, made co-sleeping and travelling so easy. I'd regard it as a great buy. We also bought the Grande which is the next size (and prob more expensive). Didn't get quite so long out of that but it smoothed the transition to grown up bed v nicely.
Love ours. Our first baby was fine just swaddled but baby 2 hated being swaddled so we got a sleepyhead when he was less than a week old. He slept amazingly in it and started going 12 hours through the night at 4.5 months old (he was only having 1 wake up previous to this anyway) The only thing I'm a bit concerned about is what to do when he grows out of it which will be pretty soon. Want to wean him off of it really rather than buying the next size up, but we shall see!
