I am wondering if my dd is irritated by her grobag at night...could it be making her more uncomfotable because she finds it difficult to shift about in a find a comfy sleep position? She's 11 months and is in a 6-18month one... (which she loves and calls it her 'stars' cos it has stars on... obviously). What do you reckon... and what would i use instead...blankets pointless. tia.
