My elder daughter Serenity finally used to sleep in her room recently. The trick is I decided not to co-sleep with her. Also, she still needs her mommy watch her falling asleep, which usually takes an hour or so, since she gets up sometimes: ask me questions, etc. (delay tactic).
Little baby Sophia is getting big, she weighs about 14 lbs in 2 month check up, which doubled from her birth weight. She likes to sleep on my shoulder. Today my coworker told me one reason is she like to feel heart beat. Also sometimes she sucks my neck or upper arm. It’s normal in baby growth, I just found out from web, although I am second time dad. Never stop learning.
