Parents have revealed the lullabies they sing to send their babies to the Land of Nod.
Humpty Dumpty tops the list of nursery rhyme lullabies, whilst Moon River, from the movie Breakfast at Tiffany's, is parents' favourite song.
But there are some surprises too – including Ice Ice Baby by Vanilla Ice and Pitbull's Timber!
Research by BT found that over a third (37 per cent) of parents chose hip hop songs to sing at bedtime.
A quarter of mums sing songs from TV ads, and 15 per cent of dads sing songs from movies. More than one in 10 parents also choose pop tunes as their go-to lullaby tune.
Sporting anthems are a firm favourite with dads as a quarter choose their favourite football chant. But it's rugby anthems that most dads prefer, with Ireland's Call and Swing Low Sweet Chariot beating Liverpool FC's You'll Never Walk Alone.
Mum Giovanna Fletcher, vlogger and wife of McBusted's Tom Fletcher said: "Tom might be the singer in the house, but I like to sing a tune or two to get my baby, Buzz, to sleep. I prefer to go for classics over sporting anthems, my favourite is Edelweiss from The Sound of Music; I tend to leave the McBusted songs to Tom!"
