How do they get your attention?
mini dd has been in the habit of waking up to pee at night, she just stands next to my bed looking at me with out saying anything, and I get this feeling that "someone is watching me!" and I wake up! LOL scared the crap outta me the first few times!!
baby is still in a crib, so she just calls out.
And eldest dd rarely wakes up, but she too is just a caller.
