Hi. Just wondering whether to splash out and buy the sleepy head deluxe? My lb has gone through good and bad phases with his sleep. He's now 7 months old and goes to bed at 7. Recently he's been sleeping soundly until midnight but then wakes every 1 - 2 hours after that until we get up. He's breast fed and eats well during the day. Would the sleepyhead work or am I grasping at straws here! ? Desperate for a decent stretch of sleep!
