Well tonight i tried out my new bitti boo and fred screamed the house down for an hour untill i put a sposie on him then he went to sleep, he woke sobbing a few times but hes sleeping now .I feel so bad its only the second time we have tried a night nappy, last time he was fine going to bed just a bit bulky in a ll bamboo but he peed the bed twice so i invested in the bitti boo's. We tried them for size fitting in the day and washed before using. We will try again tommrow and hope his screaming was a coincidence and i have not traumatised him!
