I saw an ad in M+B magazine for a type of bean-bag mattress for babies, "Slumberwell baby", and they claim that it helps babies sleep as they are more comfortable. Has anyone bought one?/ Know anyone who has? My 3 month old can sleep for 8/9 hours on occasion, but usually doesn't! Last night I was woken twice, and I'm considering getting one as I'm back to work full time in 2 weeks, and need not to be exhausted. Also my job involves occasionally being called out at night, and I'm anxious to avoid my husband having to pace the floor with a wide-awake baby when I'm not there to breastfeed her back to sleep again!
