When our son was a newborn he slept in a bassinet at the end of our bed. When he woke in the night I would often stick my foot out of bed and gently rock him back to sleep.
The Lullabub may have saved my leg a lot of work.
Basically a cot rocking device, the lullabub “will gently create motion automatically in a harmonic rhythm to naturally soothe and settle babies to sleep”. With four motion simulations - mother’s womb, mother’s heartbeat, drive in the car and boat on the water, it sounds pretty comprehensive!

If only they had been available when I needed one!
