I have DS (2.3) and DD (5 months). DD sleeps in our room, is just breastfed and wakes at least once between 11pm and 7am. That in itseld isn't so bad although I would love more sleep.
But DS is now srarting to wake up when she does - he has been coming into our room and sometimes sleeping in our bed (it's OK when he does sleep, but when he wriggles there is no room left). On Sunday night DD woke at 4:30am, then DS came in at 5am and by 5:30am he had I came downstairs.
Last night, DD woke at 3:30am, DS came in to our room, DH took him back to his room and I fed DD to the sounds of a distraught DS. "Luckily" he calmed down when I went into him, but it took until 5am for him to go back to sleep and me to go back to bed. Then DD woke at 5:30am (there was more sleep after that).
Argh - I am starting to feel SO tired all the time. It does get better doesn't it???
