Has anyone tried a Snoozzzy sensory bed sheet and care to tell me about it? I've got a 2 year old who has never slept through and I'm desperate for something that might help her (Hummy Bear helps her go to sleep but doesn't keep her asleep!) and this product looks really promising as she only goes back to sleep when cuddled but generally wakes up as soon as I stop cuddling her. Thanks in advance!
