DD is just over 1 year old, tends to be in her nappy at night for about 10 hrs. Last night, she'd been in bed for four hours when she woke up screaming the place down. DH went to fetch her, found her lying in her cot, screaming, and the bed was wet. She'd managed to wet through her nappy, through her pajamas, through her sleeping bag, through the fleece blanket and onto the sheet.
How the hell did that happen?!?!?! No extra fluids to normal, and nappy was on right.
And what's the best way to make the sure mattress is clean?
