so i had finally got 5 hour stretches of sleep at night with only one wakebup from time to time, but now my 4.5 month old has learnt to roll onto her front. .. then she screams for help as she gets stuck. Back to waking evey other hour or more... so sleep deprived again!! Has anyone else had this problem with such a young baby - considering buying the sleepyhead deluxe to see if that will stop her rolling but then worried she will get stuck in that!! any advice would be appreciated as i am at my wits end now zzzzzzz
