So, this really late, but I didn't want to miss it. Baby C is actually 5 months now, but here's a little update about her 4th month.
Personality: Still the happiest, sweetest baby during the day, but not such a happy girl at night. See sleep below.
Likes: This month Baby C was so much more smiley! She's also squealing and laughing. On the night she turned 4 months old, Baby C went with me to our neighborhood Christmas party with me and one of the ladies had her rolling. It was the sweetest little sound! We started going to the gym this month and she seems to do really well in the day care.
Dislikes: Anyone leaving the room. If you walk away from her she starts talking to herself or, more often, crying. She also dislikes sleeping more than an hour at a time at night.
Sleeping: AHHHHH! Baby C was sleeping really well until early November, then not. At. All. Baby girl woke up every 1-2 hours during the night, and would only go back to bed if I fed her. Not cool. She was still great during the day, but nights were a total mess.
Eating: Baby C was eating so much, or at least so often at night, and still eating well during the day. Baby C eats about every 3 hours during the day. Her last feeding before bed E gives her a bottle. At Baby C's 4 month check up she was 15 pounds, 12 ounces so she is a big baby! (Also 25 inches long.) None of my girls have been small babies, but Baby C was a full pound bigger than Miss A at the same age. I guess eating all night will do that to you.
