Who knows why she said that? Maybe because she's tired because S woke up and she had little sleep? Sleeping with a toddler in a bed is difficult enough, sleeping on a sofa near impossible.
I would have been cranky, too. Good that you didn't react to it. Do you sometimes get up and get him when he wakes in the night?
(sorry if you've discussed this, haven't read the whole thread)
I do get up with S sometimes, but no where near as often as W does. She has that "mother's hearing" and wakes up any time he makes a noise. She's often up to comfort him before I even realize he's woke.
