Connie slept through the night 8pm-7am (with the exception of a quick 60ml bottle at 11pm that I woke her up for) for the first time last night . I changed her at 11pm but obviously by 7am when I woke her up (I flushed the loo ) her nappy was saturated. Should I be waking her to change her half way through the night or is it OK to leave her as I don't want her bum geting sore?
